Curious isolation: new butterfly species discovered

Due to its specific ecological associations and low genetic diversity, this butterfly may soon face challenges with climate change adaptation.

In the heart of Canada’s Rocky Mountains, an unassuming yet remarkable butterfly has been quietly flying under our scientific radar for years. With a wingspan of an inch to an inch and a half, and wings that are brown on top and greyish brown with black spots below, this population was long thought to belong to the Half-moon Hairstreak (Satyrium semiluna). However, the isolated hairstreak butterflies of Blakiston Fan in Waterton Lakes National Park, Alberta, have now been recognized as a distinct species: Satyrium curiosolus, or the Curiously Isolated Hairstreak.

A recent study by an international collaborative team, published in ZooKeys, uncovered the unique evolutionary history of this population. The results were striking: Satyrium curiosolus has been completely isolated from its closest relatives for quite a while—possibly up to 40,000 years— becoming more and more genetically and ecologically unique along the way.

The science behind the discovery

“Our whole-genome sequencing of S. curiosolus revealed strikingly low genetic diversity and exceptionally high levels of historical inbreeding compared to the geographically nearest S. semiluna populations in British Columbia and Montana, more than 400 km distant,” says co-first author Zac MacDonald, a La Kretz postdoctoral researcher at University of California Los Angeles Institute of the Environment and Sustainability. Despite its small population size, genetic data suggest that S. curiosolus has likely maintained itself as a stable, independent lineage for tens of thousands of years. “Like the Channel Island Fox, S. curiosolus may have purged some of its harmful recessive genetic variation through a long, gradual history of inbreeding, allowing it to persist as a small and completely isolated population today,” MacDonald adds.

Satyrium curiosolus is found in a distinct habitat unlike any other population of S. semiluna that we know of. While its relatives thrive in sagebrush steppe, S. curiosolus occupies a single alluvial fan that is more accurately described as prairie-grassland, where it associates with different plants and ant species. Satyrium curiosolus relies exclusively on silvery lupine (Lupinus argenteus) for larval development, a plant not known to be used by S. semiluna populations in British Columbia.

“Furthermore, we recently discovered that S. curiosolus larvae have mutualistic relationships with a particular species of ant (Lasius ponderosae), which has not been observed in other S. semiluna populations,” says James Glasier of the Wilder Institute/Calgary Zoo, who was also part of the study. Satyrium curiosolus caterpillars provide the Lasius ants with a sugary excretion called honeydew to eat, while in return the ants protect the caterpillar from parasites and predators. Caterpillars also retreat into ant galleries when disturbed, or when it gets too hot out, and adult females have been observed laying eggs right near the entrances to Lasius colonies under Silvery Lupines.

Why it matters

The recognition of S. curiosolus as a species has important implications, highlighting its unique evolutionary trajectory and emphasizing an urgent need for tailored conservation strategies.

Satyrium curiosolus faces a somewhat unique challenge: its long-term isolation has resulted in very low genetic diversity, which means that the species has a reduced potential to adapt to changing climatic conditions. While conservationists often consider genetic rescue—introducing individuals from related populations to boost genetic diversity—as a solution to low genetic diversity, the distinctiveness of S. curiosolus raises concerns about potential outbreeding depression when mixed with S. semiluna. It is likely that the two species are not even reproductively compatible, meaning S. curiosolus may be on its own. Conservation efforts must now consider new solutions, such as establishing additional S. curiosolus populations, to help this butterfly persist as climate change threatens ecological change at Blakiston Fan.

A case study in genomics and conservation

“The discovery of S. curiosolus is a powerful demonstration of how genomics is revolutionizing taxonomy and conservation,” remarked co-first author Julian Dupuis, an Assistant Professor in the Department of Entomology at University of Kentucky. “While traditional taxonomic methods often rely on morphology alone, our study underscores the importance of integrating genomic and ecological data to uncover hidden diversity. With the rise of genomic tools, previously unrecognized species like S. curiosolus are being discovered, highlighting the need for conservation strategies that account for cryptic biodiversity.” Dupuis adds.

Collaboration in conservation

The Curiously Isolated Hairstreak reminds us that even the smallest and most overlooked species can hold extraordinary scientific and conservation significance.

“Our studies on S. curiosolus and S. semiluna highlight the importance of collaboration between academic scientists, nonprofit organizations, and conservation managers. All of this work was made possible through partnerships between academic researchers, Parks Canada, and the Wilder Institute/Calgary Zoo. By combining expertise in genomics, field ecology, and conservation management, we were able to produce findings that not only reshape our understanding of biodiversity but also provide actionable insights for species protection. Moving forward, these interdisciplinary collaborations will be critical for tackling complex conservation challenges and ensuring the long-term survival of species like S. curiosolus,” added MacDonald.

The future of Satyrium curiosolus

Recognizing S. curiosolus as a distinct species is just the beginning, the researchers say. Future research should explore its evolution and interactions with other species like host plants and ants. Additionally, long-term monitoring by Parks Canada and the Wilder Institute/Calgary Zoo will be essential to assess how this species copes with climate change and what conservation actions are appropriate. “This is a wonderful example of how such monitoring can connect diverse approaches and impactful answers to a simple question like ‘that’s odd – why is it there?’”, says anchor author Felix Sperling, a professor at the University of Alberta and curator of the U of A’s Strickland Museum of Entomology.

“For now, the Curiously Isolated Hairstreak reminds us that even the smallest and most overlooked species can hold extraordinary scientific and conservation significance,” the researchers say in conclusion.

Spider-eating spiders: new ‘pirate’ species discovered in China

Also known as cannibal spiders, two new species have been discovered in Guizhou Province.

China’s Guizhou Province has long been known for its remarkable biodiversity, but a recent study in Zoosystematics and Evolution has shed light on some of its creepier, lesser-known inhabitants: pirate spiders.

What is a pirate spider?

The name ‘pirate spiders’ refers to species belonging to the family Mimetidae. Also known (misleadingly) as cannibal spiders, they earned their name because of their araneophagic (spider-eating) nature.

These eight-legged predators don’t spin webs to catch prey; instead, they infiltrate the webs of other spiders and mimic the vibrations of prey or potential mates, then ambush the unsuspecting hosts when they come to investigate.

A recent research paper by Zhang et al. offers the most comprehensive survey to date of the pirate spider genus Mimetus in Central Guizhou, including two new species, bringing the provincial total to eight and giving Guizhou the highest Mimetus diversity in China.

China’s new species

Mimetus guiyang

Discovered in Guiyang City, this species is known only from females collected via pitfall traps. Its most distinctive feature is the presence of large bubble-shaped ossified hair bases on the abdomen, a rarity among known Mimetus species. Its genital morphology and body patterns make it easily distinguishable from close relatives.

Mimetus lanmeiae

Also found in Guiyang, this species was observed perched on a spider web, likely in the act of mimicry. Its unique palpal structures and small body size (~2.14 mm) distinguish it from other known Mimetus species. The name of the species honours the mother of the specimen collector. Hopefully this was meant as a compliment.

Other findings

New records: The researchers recorded two previously known species (M. caudatus and M. sinicus) for the first time in Guizhou, expanding their known range.
Rediscovery and redescription: M. caudatus, previously known only from male specimens, now has its female described in detail.
Molecular insights: DNA barcoding (COI gene sequencing) was used to support species identification and match males and females – a critical step for accurate taxonomy, especially given the subtle differences between males and females in Mimetus.

Exquisite but endangered: new ‘fairy lantern’ flower discovered in Malaysia

The tiny new Thismia species is threatened by habitat degradation.

Species belonging to the genus Thismia are some of the strangest and most magical-looking in the plant kingdom, which has earned them the nickname ‘fairy lanterns.’

No exception to the rule, a newly discovered Thismia species from eastern Peninsular Malaysia looks like something that belongs in a fantasy world.

Take a look below.

Thismia aliasii.

Standing just 11 cm tall, Thismia aliasii is an easy-to-miss and Critically Endangered new species described in the open-access journal PhytoKeys.

The genus Thismia consists of plants that are mycoheterotrophic, meaning they do not photosynthesise and instead rely entirely on fungi for their nutrition. The unusual flowers seen on Thismia species facilitate specialised pollination mechanisms involving small insects such as fungus gnats.

Sun-shunning thief: new plant species robs underground fungi to survive

Thismia aliasii was first documented by co-author Mohamad Alias Shakri in 2019 during a field expedition in Terengganu’s Chemerong Forest Eco Park, not far from a hiking path.

“The discovery of Thismia aliasii is very interesting as it was found in a mountainous region known for its natural beauty. The discovery was made on the edge of a popular mountaineering trail, but, remarkably, the species was first recognised by Alias.

“It was not easy to obtain specimens for further study as its habitat is on the mountain and COVID time delayed search efforts. Fortunately, targeted field work to find this plant was successful with the support of NAGAO.”

Thismia aliasii is provisionally classified as Critically Endangered (CR) under the IUCN Red List criteria, with only five individuals observed across multiple surveys. The primary threats to its survival stem from habitat degradation due to increasing hiking activities in the region.

This discovery adds to Terengganu’s reputation as a hotspot for Thismia diversity, being home to 13 species of the genus, including six endemics.

Moth collected by Alfred Russel Wallace is key to describing 11 new species

“We have not only revived Francis Walker’s species Topiris candidella, from 1863, but also expanded our understanding of an entire group of small white moths.”

A moth neglected by experts for a century is found to have been collected by Alfred Russel Wallace 169 years ago
Cutting-edge techniques allowed scientists to show the moth as belonging to a genus comprising 14 species, 11 of which are new to science
One of the new species has been named after Greta Thunberg

Scientists at the Natural History Museum (NHM), London, have discovered that a long-overlooked moth specimen in the Museum’s collection was in fact collected by explorer and naturalist, Alfred Russel Wallace, in 1855. This was at the same time as he was formulating his own revolutionary ideas on the origins of species which he would go on to share with Charles Darwin.

The small white moth, Topiris candidella, was described in 1863 by Francis Walker but was dismissed in 1927 by leading entomologist Edward Meyrick as “better neglected” having suffered substantial damage due to historic storing practices. The moth has remained overlooked for nearly a century, until now.

Using a cutting-edge DNA sequencing method, NHM scientists extracted genetic material from a single fragment of one of the specimen’s remaining legs and connected it to a group of moths found throughout South East Asia.

The scientists were able to prove that rather than being a single neglected species, Topiris is in fact a genus of 14 species, including 11 species which are new to science and described today in the paper published in ZooKeys.

One of these species is named Topiris thunbergella, in honour of Greta Thunberg and her work in raising awareness of the environmental pressures on the native forests of South East Asia.

Dr David Lees, Senior Curator for Microlepidoptera at the Natural History Museum, adds, “This discovery highlights the incredible potential of modern DNA analysis to reveal the evolutionary history of species, even from fragmented and long-forgotten specimens.

“By applying this innovative sequencing technique, we have not only revived Francis Walker’s species Topiris candidella, from 1863, but also expanded our understanding of an entire group of small white moths.”

During their research, David and fellow moth expert, Mark Sterling, found that a hidden label under the pin of the broken moth bore the handwritten letters “SAR”, a clue that this moth had been collected by Alfred Russel Wallace as part of over a thousand moths he collected at Rajah Brooke’s Forest retreat.

Paralecta rosiflora
Topiris thunbergella
Topiris salva

This was in December 1855, just months before he published his ‘Sarawak Law’ paper, which eventually led to a joint reading (at Darwin’s request) of their theories of evolution through natural selection.

Beyond the scientific breakthrough, the study has wider conservation implications. Of the 24 species reviewed in their paper, only three have been recorded since 2000, highlighting the urgent need for biodiversity monitoring in this region.

Mark Sterling added, “The 80 million specimens currently held in the Natural History Museum’s collections continue to be a critical resource for understanding biodiversity and assessing the effects of environmental change.”

In pursuit of a poison frog — and a culturally appropriate name

Researchers tracked down a new species along Colombia’s Pacific coast, naming it in honor of an Afro-Colombian music style.

When Rebecca Tarvin was a graduate student studying toxins in the skins of poisonous frogs, she and her colleague Mileidy Betancourth-Cundar collected a frog in Colombia that they suspected was a new species. It differed in coloration from a similar Colombian frog in the genus Epipedobates and had a different mating call.

In 2022, eight years later and a newly appointed assistant professor of integrative biology at the University of California, Berkeley, Tarvin met up with Colombian biologists to collect more of these frogs and confirm a new species. Such “holotype specimens” are necessary to document a new species for posterity. Collecting specimens and identifying new species also helps scientists track the impact of environmental changes and understand the evolutionary origin of traits such as skin toxins, which may one day have medical uses.

Collecting the frogs was easy; they seem to thrive along roadsides and in semiurban areas. But what to name the species? A Colombian colleague played for the team a tape of local marimba-based music called bambuco, and one style, called bambuco viejo, or currulao, stood out. The name Epipedobates currulao seemed appropriate, and with this month’s publication of a paper describing the new species in the journal ZooKeys, it’s now official.

“We ended up going with currulao because we liked how it brought in the human perspective,” Tarvin said. “The frog is part of the sound landscape; when they call, it’s part of the background noise in the region. Similarly, currulao is more than just a genre of music. It’s also the cultural practices around the music, the gathering, dancing and the relationship-forming aspects of the experience.”

A performance by Cantadoras del Pacifico at the 2009 Smithsonian Folklife Festival. Currulao, which combines marimbas and drums, is popular in black communities along Colombia’s Pacific coast.

Tarvin is still investigating the toxins produced by frogs in the genus Epipedobates, which is small, containing about eight species, but is the most recently evolved group of poisonous frogs in South America. By comparing the genetics of these frogs with other poison frog groups, she hopes to understand how their chemical defense technique evolved. Most poisonous animals are brightly colored to advertise their unpalatability, such as the Monarch butterfly’s bright orange color and the gaudy orange, black and blue of poison dart frogs. But Epipedobates frogs are more subtly colored, if not downright drab. Perhaps, she said, bright coloration evolves after the frogs develop their toxic defenses.

Epipedobates acquired its chemical defenses more recently than any other group in the poison frog family and shows the largest range in color and defense, Tavin said, but they’re also interesting because of how they acquire their toxicity.

“What’s unique about poison frogs, specifically, is that they sequester toxins from their food, so it’s an entirely different kind of defense that requires an entirely different physiology, compared to venom-producing animals, like snakes and bees,” she said. “Poison frogs eat arthropods that have small amounts of chemicals that can be either toxic or distasteful. And then they accumulate those to levels that become relevant for their own predators.”

Tarvin offers one piece of advice: Because they’re covered in poisons, don’t lick your fingers after picking one up.

New blazing star discovery highlights the power of citizen science

The rare plant was identified thanks to photographs uploaded to iNaturalist.

Discovered in the Andean cloud forests of northern Peru, a new species in the blazing star family (Loasaceae) has reinforced the vital role of citizen science in plant research.

An international research team collected, identified and documented the rare plant after seeing photographs uploaded by Peruvian naturalist, Carlos Pérez Peña, on the citizen science platform iNaturalist. Assigning the species the name Nasa katjae, they published the discovery in the open-access journal PhytoKeys.

Nasa katjae has striking scarlet-red flowers adapted for hummingbird pollination and is endemic to a single forest near Colasay in the Cajamarca region of Peru, not far from a populated area. Due to its extremely narrow range, it is likely particularly vulnerable to the threat of habitat loss.

The discovery highlights the importance of protecting the remaining pristine habitats in the Amotape-Huancabamba Zone, a biodiversity hotspot home to many rare and isolated species. The team behind the study emphasise that, without immediate conservation efforts, these ecologically fragile regions could be lost to agricultural expansion and climate change before they are fully understood.

Lead author Dr Tilo Henning of the Leibniz Centre for Agricultural Landscape Research remarked on the significance of the find: “If we have overlooked this striking plant, think about what we have missed in more unobtrusive organismal groups such as mosses, fungi and insects.”

“Discovering such a conspicuous flowering plant in a forest directly adjacent to a larger human settlement signifies that we have not even begun to fully map the biodiversity of some regions. We urgently need more taxonomists and funding to meaningfully tackle this.”

While some areas in northern Peru have recently received formal protection, the forest fragment in which Nasa katjae is found remains unprotected. The authors of the study urge decision makers to take action to safeguard these habitats before it is too late.

The discovery of Nasa katjae displays the power of digital tools and citizen science in biodiversity research. Platforms like iNaturalist prove invaluable in detecting and documenting rare species, complementing traditional fieldwork and accelerating new discoveries.

The woolly devil: a landmark U.S. plant discovery

Belonging to the sunflower family, the tiny plant was found in Big Bend National Park, Texas.

Based on this press release by the California Academy of Sciences.

Researchers have discovered the first new genus and species of plant in a U.S. national park for nearly 50 years.

Described in the OA journal PhytoKeys, the new-to-science woolly devil (Ovicula biradiata) is a member of the sunflower family, despite looking quite different to its sunburst-shaped relatives.

Scientists from the California Academy of Sciences, Big Bend National Park, Sul Ross State University, and Centro Interdisciplinario de Investigación para el Desarrollo Integral Regional (CIDIIR) made the discovery in Big Bend National Park, Texas.

The national park is located within the Chihuahuan Desert, the largest and most biologically diverse warm desert in North America, and is a highly studied floristic region.

“While many assume that the plants and animals within our country’s national parks have probably been documented by now, scientists still make surprising new discoveries in these iconic protected landscapes,” says corresponding author and Academy researcher Isaac Lichter Marck, PhD.

Park volunteer Deb Manley was first to observe the plant in March of 2024 by who uploaded the unknown species to the community science app iNaturalist, where an international community of botanists assembled to identify the mysterious flower.

Known to botanists as a “belly plant,” or a small, discreet plant that can only be properly observed by lying on the ground, this distinctive wild flower with furry white foliage and maroon ray florets is an ephemeral species that only blooms after rain. It thrives in harsh rocky habitats with scant rainfall and grows alongside a variety of drought-tolerant shrubs, such as ocotillo, hedgehog cactus, and creosote.

Researchers have only observed the plant in three narrow locations across the northernmost corner of the park, and it is possible that populations of the species are already diminishing.

“Plants that thrive in deserts are often quite unique, having evolved specific mechanisms to withstand the extreme drought-and-deluge conditions of these arid landscapes—from water-storing structures to rapid life cycles triggered by rain,” says Lichter Marck.

“But as climate change pushes deserts to become hotter and drier, highly specialized plants like the woolly devil face extinction.”

The plant’s woolly appearance and striking red petals inspired the name Ovicula biradiata. Ovicula, meaning “tiny sheep,” refers to the thick, white hairs that cover the plant’s leaves and honors a more iconic endangered species in Big Bend: the bighorn sheep (Ovis canadensis). Biradiata, or “bi-radial,” refers to the two ray florets in each of the plant’s flowers. Researchers working with the plant affectionately dubbed the fuzzy flower the “woolly devil,” which has become its suggested common name.

“Now that the species has been identified and named, there is a tremendous amount we have yet to learn about it,” says Big Bend National Park botanist Carolyn Whiting.

“I’m excited to discover whether there are other populations in the park, the details of its life cycle, what pollinates it, and whether we’ll observe it this spring, given the current drought.”

Researchers are now investigating the woolly devil’s potential medicinal properties.

“Under the microscope, we noticed specific glands that are known to possess compounds with anti-cancer and anti-inflammatory properties in other plants within the sunflower family,” says Academy co-author Keily Peralta.

“While further research is needed to determine these properties, this discovery underscores the potential knowledge we stand to gain from preserving plant diversity in fragile desert ecosystems.”

The Ghibli fish: new ‘painted’ species named after Princess Mononoke

The deepwater tilefish was first spotted by researchers on an online seafood market.

Picture in your mind the discovery of a new species.

What do you see? Researchers cutting through dense, untouched rainforests? Perhaps a submarine plunging into a deep-sea trench, illuminating a new world?

Well, it’s not always quite so dramatic. In fact, researchers in China discovered Branchiostegus sanae when they were scrolling through online seafood markets and noticed some deepwater tilefish with unique cheek patterns.

These red-and-white facial markings reminded the research team of the Studio Ghibli character San from Princess Mononoke, whom they chose to honour in their naming of the species.

Published in the open-access journal ZooKeys, Branchiostegus sanae is a deepwater tilefish belonging to the family Branchiostegidae. Researchers confirmed its new-species status using genetic analysis, and chose “sanae” as the specific epithet (that’s the part that differentiates species within a genus), in a nod to Hayao Miyazaki’s animated creation.

“Finding a new species in this group is a rare and fortunate event, especially one as distinctive as Branchiostegus sanae.

“In Princess Mononoke, San is a young woman raised by wolves after being abandoned by her human parents. She sees herself as a part of the forest and fights to protect it. The film delves into the complex relationship between humans and nature, promoting a message of harmonious coexistence between the two: something we hope to echo through this naming.”
Lead author, Haochen Huang.

The Chinese fishermen who sell the new-to-science species call it the“鬼马头鱼” (ghost horsehead fish), and this also contributed to the species name because, fittingly, “Mononoke” (もののけ) refers to supernatural spirits in Japanese folklore.

As their name suggests, deepwater tilefish are found at great depths, with some species found 600 m below the surface. They are important food fish, commonly found in seafood markets in East and Southeast Asia.

Branchiostegus sanae is far from the only new species discovered at a seafood market. Indeed, a new giant isopod was recently dicovered in the same way – and also recieved a pop-culture inspired name. Check it out below!

The Slytherin snake

10 points to Slytherin!

When naming a newly discovered green pit viper species from the Himalayas, researchers sought inspiration from the Harry Potter franchise.

Fittingly, they settled on Trimeresurus salazar, a reference to Salazar Slytherin who founded the serpent-crested Hogwarts house bearing his name.

The snake in a ski mask

Slithering around in style.

Rhynchocalamus hejazicus is a recently discovered and secretive snake species from the Hejaz region of Saudi Arabia.

Upon the species’ discovery, researchers dubbed the stylish serpent “the missing piece of the puzzle” as it fills a large distribution gap for its genus.

The eyelash viper

Separating snake species.

An expedition into the jungles and cloud forests of Colombia and Ecuador revealed five dazzling new species of eyelash vipers, previously misidentified as one species.

Published in Evolutionary Systematics, the study received global attention from publications such as National Geographic thanks to the taxonomic importance and visual appeal of the research.

The shovel snake

Who ever said snakes can’t be cute?

Two species of African shovel-snout snakes, Prosymna confusa and Prosymna lisima, were published as new species in ZooKeys back in 2022.

Endemic to Angola, the snakes have unique beak-like snouts that allow them to dig into sandy soils. They also have backward pointed lancet-shaped teeth that they use for cutting open lizard eggs.

As they spend the majority of their time underground, these species were not the easiest to study, but they are certainly a treat for the eyes when they surface their wedge-shaped heads!

Inspiring a new generation of taxonomists

New species of Australian miracine wasps described with school students as part of the Insect investigators citizen science project

Guest blog post by Mollie Slater-Baker

It is estimated that only around 20% of the world’s insects are formally described. A formal description is the foundational understanding of a species, including a scientific name, information on how to identify the species, its biology, and where it can be found. With such a large proportion of our insects lacking this foundational information, we are left viewing the insect world through a very small window. This has major implications for conservation of insects and the ecosystems in which they play integral roles. It also limits our understanding of our natural resources, with the study of insects being valuable in a variety of fields, from healthcare and biochemistry, to biological pest control, to insect-inspired engineering.

Unfortunately, with a worldwide lack of taxonomic experts, limited funding, and the immense scale of describing the world’s insects, documenting our insect diversity before it’s lost to extinction is a considerable challenge. But this is where community engagement and citizen science can shine.

Experts in insect taxonomy “threatened by extinction” reveals the first European Red List of Taxonomists

The Insect Investigators citizen science project, which ran in Australia in 2022, aimed to involve schools throughout the taxonomic process, to contribute to large-scale collection and documentation of Australian insects, while fostering an appreciation for insect diversity and the role of taxonomy. Fifty rural schools from Queensland, South Australia, and Western Australia participated by setting up Malaise traps (tent-like passive insect traps) to sample local invertebrates near their schools over four weeks. This project resulted in over 60 thousand insect specimens being collected from often under-sampled, more remote parts of Australia. The resulting specimens are preserved and deposited in Australian museums for future research, including taxonomic work.

Malaise traps set up at Kwoorabup Nature School (left) and Beerwah State High School (right) to sample insects as part of the Insect Investigators project.

Through this project, several schools were involved in collecting a rarely collected group of parasitoid wasps belonging to the subfamily Miracinae (aka miracine wasps). These tiny wasps (typically 1-2mm in length) are very difficult to collect using traditional methods, though they appear to be quite diverse in Australia. As parasitoids, miracine wasps require an invertebrate host to complete their lifecycle. For miracine wasps, this host is a leaf-mining caterpillar – the kind that eats small twisting tunnels on the inside of leaves. The wasps lay their eggs inside these caterpillars, and the wasp larvae hatch and eat the caterpillar from the inside out!

‘Insect soup’ – specimens collected via Malaise Trap at Kwoorabup Nature School.

Due to their caterpillar-eating biology, and the fact that they are picky eaters, usually targeting a specific species, these wasps can be used to control pests. For example, the miracine wasp species Mirax insularis in Puerto Rico, and Centistidea striata in Brazil, are known to attack coffee leaf-miners, a major pest of coffee plantations – so you may have one of these wasps to thank for your morning coffee!

As part of this project, we engaged with schools to involve them throughout the process of describing the miracine wasps they had collected. First, we ran in-person and online or hybrid workshops with the students to teach them about the new wasp they had discovered, and the taxonomic process involved in describing and naming it. The students then brainstormed a variety of creative names for the new species, which were collaboratively curated and voted upon to arrive at the final species names.

From Queensland, we have Mirax supremus, meaning ‘highest’ in Latin, named after the Pinnacle program at Beerwah State High School, which the students were a part of.

From South Australia, comes Ceduna Area School’s species, Mirax ceduna, named after the school and town the wasp was collected from (colloquially known as the ‘golden bum wasp’).

And from Kwoorabup Nature School in Western Australia (WA), Mirax kaatijan, meaning knowledge/learning in the Noongar language of the south-west region of WA, to represent the new knowledge the students had learnt about insect diversity, and the importance of knowledge about our insects.

Though the descriptions themselves are a small step towards the immense task of describing Australia’s insects, it was inspiring to see the students and their communities really engage with the process and build a connection with their local insects, and an appreciation for these tiny, often-overlooked wasps. We hope this project plays a role in inspiring the next generation of budding entomologists and taxonomists in Australia.
