During a field trip for an ecology course in a city park, lead author Ms Kaiyun Zheng was fascinated by the incredible insect biodiversity surrounding her. Insects serve as important bioindicators—their diversity and assemblage can reveal ecological processes and environmental health. However, sampling insect diversity is often challenging, requiring extensive equipment and field effort. Despite being one of the most species-rich animal groups, insects are undergoing a global decline due to habitat loss, pollution, and urbanization. Traditional insect surveys typically demand significant time and resources and are limited in scope.
Curious to find a more accessible approach, Kaiyun began exploring insect records from both expert-led field surveys and citizen science platforms such as iNaturalist. Together with her supervisor, Dr. Danny Chi Man Leong from Beijing Normal-Hong Kong Baptist University, and co-authors Dr. Mark Wong from The University of Western Australia and Dr. Toby Tsang from University of Toronto Scarborough, they posed a key question: Can citizen science reveal hidden biodiversity beyond what expert surveys have recorded?

Citizen science involves participation by people without formal scientific training, who contribute to scientific research by collecting and sharing data. In biodiversity documentation, citizen scientists can use smartphones and digital platforms to record species, helping expand scientific knowledge at scale.
Using insects as a model group, the authors examined the potential of citizen science to uncover undocumented biodiversity and discussed how large-scale citizen-contributed data could enhance ecosystem monitoring. To evaluate the strengths and complementarities of different data sources, they compared an expert dataset with a citizen science dataset.
Spatial distribution of insect observations in Macao from the citizen science dataset (iNaturalist.org) (A), along with cumulative increases in verified identifiers (B), insect observations (C), and recorded insect species (D).
In total, 1,889 insect species were recorded across both datasets, but only 462 species (24%) overlapped. The expert dataset included 1,339 species, of which 877 (65%) were not found in the citizen science records. Conversely, the citizen science dataset documented 1,012 species, with 550 (54%) unique to it. This substantial non-overlap indicates that the two approaches capture different facets of insect diversity. For example, there was relatively high overlap for insect groups such as butterflies and moths (Lepidoptera), likely due to their conspicuous appearance and popularity among observers. In contrast, groups such as wasps, bees and ants (Hymenoptera) and flies (Diptera) were underrepresented in the citizen science dataset, suggesting challenges in detecting smaller or more cryptic species.

These findings highlight the importance of integrating expert surveys with citizen science efforts to achieve a more comprehensive understanding of insect biodiversity, especially in urban areas which benefit from a high participation from citizen scientists.
Their study also highlights the unique strengths of citizen science for urban biodiversity monitoring. Residents living near parks and green spaces are ideally placed to document insect occurrences in real time across a wide range of locations. Notably, the study includes a citizen-contributed record of Mortonagrion hirosei, a Near Threatened damselfly rarely observed in Macao. This example illustrates how citizen science can detect rare or cryptic species, uncovering important biodiversity records and filling gaps left by traditional surveys, making it an indispensable tool for future biodiversity monitoring.

The Monte Gordo Grasshopper (Eyprepocprifas insularis) has proved to be a rare and elusive species: its last, and, until now, only sighting was a single specimen found in 1980. This is why researcher Dr. Michel Lecoq declared it extinct in 1996.

After more than 40 years of no records, an exciting discovery happened thanks to a holiday Rob Felix took with his fellow researcher Annelies Jacobs in Cape Verde, the insect’s only known location, “to look for birds and other interesting stuff for field biologists like us. Before going on our trip, we looked for information about this peculiar grasshopper that was thought to be extinct for a long time. We were hoping and dreaming that maybe we could find it again.”
“During a night walk on our first evening on São Nicolau to a colony of a unique seabird species, the Fea, I stumbled upon a grasshopper sitting on the path. When I looked closer in the torch’s light, I immediately recognised its unique appearance. I shouted out loud: it’s Eyprepocprifas! To my surprise, correct at once because it’s not the most easily pronounceable genus name,” he says.

In the following days, Rob and Annelies found several other specimens in Monte Gordo Natural Park and its surroundings.
Endemic to the island of São Nicolau, this grasshopper is a “living fossil,” meaning it hasn’t evolved significantly for millions of years and has few or no living relatives.

“E. insularis must have been there for a very long time and has been able to withstand the severe ecological conditions,” the researchers write in their paper, which was published in the Journal of Orthoptera Research.
This montane grasshopper has shown remarkable resilience, surviving in the challenging environment of Cape Verde’s islands and enduring periods of intense drought and strong winds that can introduce new species from the African continent.
“The rediscovery of the only endemic brachypterous (short-winged) grasshopper, Eyprepocprifas insularis, on São Nicolau, an island with a volcanic origin dating back approximately five million years, provides significant insight into the island’s ecological and evolutionary history,” the researchers write.
They say this rediscovery is a crucial first step toward the insect’s conservation: as a threatened species restricted to a small area, E. insularis might actually be closer to extinction than we think. Now that it has been found again, we have the opportunity to take steps to protect this unique species and its habitat.

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.
Satyrium curiosolus.
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.
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. Satyriumcuriosolus 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.
The discovery of S. curiosolus is a powerful demonstration of how genomics is revolutionizing taxonomy and conservation.
Julian Dupuis, Assistant Professor in the Department of Entomology at University of Kentucky
Satyriumcuriosolus 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
Title: S. curiosolus larvae being attended to by Lasius ponderosae ants.
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.

A fearsome-looking insect commonly referred to as “winged wētā” may look like a flying wētā, but it is not a wētā at all. It belongs to the family of the raspy crickets, which is not native to New Zealand. Like all of its family members, it has the ability to secrete silk from its mouth parts, which it uses to build shelters in foliage.

The “winged wētā” was first detected in Auckland in 1990. Within thirty years, it had expanded its range north to Cable Bay, Northland; east to Coromandel Peninsula, and south to Raglan, Waikato. While sightings in New Zealand became more and more numerous, the insect remained unidentified. New Zealand entomologist Danilo Hegg recently travelled to Queensland, Australia, to trace the “winged wētā” back to its population of origin and put a name to the species. In a peer-reviewed study now published in the Journal of Orthoptera Research, Hegg showed that the insect originates from the montane rainforests south of Brisbane, at the border of Queensland and New South Wales.
Collection localities in New Zealand and Australia.
“The insect is heavily built, has relatively short wings, and is a poor flyer,” says Hegg. “While Australian butterflies do occasionally reach our shores carried by westerly winds, the 2,300km journey across the Tasman Sea is almost certainly too much for the winged wētā. It is highly unlikely that it would have reached New Zealand by natural means”. Australian insects carried by the wind may land anywhere between Cape Reinga and Rakiura / Stewart Island. The fact that the “winged wētā” was first detected in Auckland, New Zealand’s largest import hub, only adds weight to the hypothesis of an accidental introduction by anthropogenic means.
Not only has the “winged wētā” been expanding its range in New Zealand; it has also been building up numbers. Its population density has at least quintupled in Auckland during the past twelve years. And like many other invasive species, it appears to be found in higher numbers in its new territory than in its country of origin. “In Queensland, I could spend a night out and find one or two individuals at most. In Auckland, I was able to capture seven specimens in a two-hour walk” says Hegg.

The “winged wētā” is an omnivore and an agile hunter. Strictly nocturnal, it prowls in the foliage in trees and pounces on any invertebrate that is small enough for it to tackle. Observations conducted in captivity and in the wild have shown that the “winged wētā” preys on just about anything that moves at night. Including juvenile Auckland tree wētā, one of New Zealand’s largest insects.

Given its high population density and its predatory habits, there are concerns the invasive insect could have an impact on New Zealand’s native invertebrate wildlife. “There is still a lot we don’t know” says Hegg “we need to study its diet in the wild, and we need to understand whether the winged wētā is also taking hold in intact native forest habitats, or only in urbanised areas, where the majority of the sightings are. But it poses a threat that needs to be taken seriously”.
New Zealand’s invertebrates are already being decimanted by introduced rodents, mustelids, hedgehogs, cats and wasps. The Australian winged wētā is only going to add to their woes.

The thin, flexible, and mobile ovipositor of some female insects, perfected over thousands of years of evolution, can carry substances and drill into various substrates. Although its structure is well studied, many of its functions remain a mystery.
Researchers from Saratov State University and Moscow State University spotted interesting, unusual oviposition behaviour in the parasitoid wasp Eupelmus messene: it used its ovipositor to drill through the wall of a polystyrene Petri dish and lay an egg outside the dish.
Drilling with the ovipositor through a plastic wall of a Petri dish by Eupelmus messene (A), a newly laid egg into the external environment (B), and UV fluorescent biological substance inside the perforations (C). ov – ovipositor, per – perforation, egg – egg.
This is the first time such behaviour has been observed and recorded.
E.messene is a parasitoid of the gall wasp Aulacidea hieracii, which forms a gall on the stems of the hawkweed Hieracium×robustum. The female of E.messene then drills the walls of the gall with its ovipositor in search of a gall wasp larva and, upon finding it, lays an egg next to it.
The researchers reared 56 females from galls of H.×robustum collected near Saratov, Russia. Of them, they placed 18 in Petri dishes without host galls, and later observed five of those wasps drilling into the walls of the Petri dishes.
The team followed the behaviour of one wasp: drilling each perforation in the polystyrene wall took more than two hours, during which the insect often paused to eat, drink water, or wash. In the end, it managed to completely pierce the plastic wall and lay an egg on the outside of the Petri dish. It drilled multiple holes, even after being transferred to a different Petri dish.

“We distinguished four steps of drilling: pushing movements, rotational movements, ejection movements, as well as the cementing step. However, in natural gall, we never observed ejection movements. We suppose that such a type of movement is required to rake out plastic particles, which is unnecessary for more elastic plant gall substrate,” write the authors in their study, which was published in the Journal of Hymenoptera Research.
After laying the egg, the female carefully cemented the drilled perforation with an unknown biological substance, likely to keep it safe from the impacts of changing temperatures, water, and microorganisms.
Unlike galls, which usually have an opaque and dense structure, the transparent Petri dish provided a clear view of the whole drilling and oviposition process, allowing the researchers to study it closely.
It is still unknown why the wasp behaved this way, but the scientists believe we can learn a lot from this observation: “Studying in detail the drilling behavior of parasitic mycrohymenopterans can be useful in medicine for the creation of minimally invasive guided probes in neurosurgery, the development of orthopedic surgical instruments, needle biopsies using functionally graded tools,” they write in their paper.

Jake Lewis, an entomologist in the Environmental Science and Informatics Section at the Okinawa Institute of Science and Technology (OIST), is fascinated by weevils, a diverse group of beetles that includes many species with elephant trunk-like mouthparts (called a rostrum). Weevils provide various ecosystem services such as pollination and decomposition, but some species are serious pests known to decimate crop fields and timber forests.

Using x-ray microtomography, a 3D imaging technique that uses x-rays to visualize cross sections of the internal structure of objects, Lewis and his collaborators digitally removed scales that cover the cuticle of the weevils. They found that the underlying cuticle differs significantly between species and can therefore be used for taxonomic and classification purposes. Using this technique in combination with traditional light microscopy and DNA barcoding, they discovered, described, and named 12 new weevil species from Japan, Malaysia, Vietnam, and Taiwan. These species range from 1.5 – 3.0 mm in length and are comparatively quite small weevils.
Two of these new species are present in Japan: Aphanerostethus magnus (Oo-daruma-kuchikakushi-zoumushi) and Aphanerostethus japonicus (Nippon-daruma-kuchikakushi-zoumushi). One of these, Aphanerostethus japonicus, is also found in Yanbaru National Park, Okinawa. This is the first time x-ray microtomography has been used to remove obscuring scales to examine underlying differences in morphology for taxonomic purposes. The findings from this study have been published in the open-access journal ZooKeys.

The researchers showed that removing scales using x-ray microtomography reveals significant morphological differences between species, which cannot be easily observed using other methods. Consequently, this technique may gain more popularity as a tool for identifying new insect species, especially those covered in scales or debris.
Lewis, OIST’s Insect Collection Manager and lead author of the paper, examined specimens from collections in Canada, Germany, Japan, Malaysia, Taiwan, and the Netherlands. One of the primary goals was to investigate the use of x-ray microtomography as a tool in weevil taxonomy. The genus Aphanerostethus was poorly studied in the past, but many undescribed species were discovered in museum collections around the world, including the two new species from Japan.
X-ray microtomography generated 3D models of weevil species from the genus Aphanerostethus with the right elytron (forewing) removed, revealing differences in the length, width, and pattern of veins in the hindwing. A lateral view of the full body is shown below each closeup for reference. The red, blue, and yellow arrows indicate the base, midpoint, and apex of the hindwing, respectively.

Multiple methods to find new species
The researchers used traditional methods such as light microscopy and dissections to observe differences between species, including the scales along the elytra (back), leg spines, and the shape of the rostral canal (a canal that protects the rostrum). They also used DNA barcoding to analyze their genes and create a phylogenetic tree of eight of the species. Some species were not as easy to separate based on morphology alone, but as the gene sequences differ between species, the phylogenetic tree was informative and provided additional evidence of new species.

This helped Lewis and his team verify their predictions about species classification by using DNA analysis instead of only physical traits.

Although the above methods are standard practice in taxonomy, the researchers’ use of X-ray microtomography was novel and was successfully used to examine the structure of not only the hidden cuticle, but also the hindwings. Aphanerostethus weevils have lost the ability to fly due to the gradual reduction of their hindwings, however the degree of reduction was shown to differ between species. Normally, specimens would have to be dissected to view the hindwings, but because x-ray microtomography allows for non-destructive examination of internal anatomy, it is invaluable when working with rare or precious specimens that cannot be dissected or altered.

The presence of partially reduced wings in some species offers a fascinating glimpse into the ongoing process of evolutionary change: “Some species have almost completely lost their hindwings, while others still have non-functional half-wings with remaining vein patterns. The differing degrees in hindwing loss is not only useful for taxonomy and systematics, but also shows how different species within the same group can be at different stages of losing a historically highly important organ that played a crucial role in insect evolution,” Lewis explained.
Investing in Japan’s natural heritage
The discovery of new weevil species can be challenging for two main reasons. Firstly, weevils are incredibly diverse, making complete cataloging time consuming and tedious. Secondly, many weevil species are highly host-specific, may only inhabit very particular microhabitats, and may only be active for a short period of time as adults. For example, some species feed on a single tree species and may only occupy a certain part of a tree, such as the canopy. Furthermore, some species of weevils are strictly nocturnal and rarely observed during the daytime.

This extreme specialization and variation in natural history means that unless researchers investigate at night and day, across seasons, and focus on specific parts of many different plant species, they will inevitably overlook certain species.
Dr. Dan Warren, a research fellow at the Gulbali Institute for Applied Ecology and former leader of the Environmental Science and Informatics Section, emphasized the importance of investing in specimen collections: “These specimen collections are crucial for discovering new species and documenting biodiversity changes, both from human activities and natural cycles. They are essential tools for scientific research and conservation biology,” he stated. “Without proper support for them and the people who maintain them, we risk losing irreplaceable information on species and ecosystems, potentially before we even discover them.”

“These new weevil species are part of Japan’s natural heritage, and although still poorly known ecologically, discovering and naming them is the first step towards an understanding of their biology,” Lewis added. Protected areas like Yanbaru National Park, home to the newly discovered A. japonicus, are essential to the protection of the island’s rich and endemic biodiversity.

The demand for the digitization of natural history collections has increased with the advancement of imaging technologies. Large collections composed of millions of insect specimens are exploring efficient strategies and new technologies to digitize them. However, many of these new systems are quite elaborate and expensive, creating a need for more affordable and easy-to-use equipment.
75-by-47-cm foam platform with pinned insects in dorsal and lateral positions.
Creating a digital image for every specimen is an essential part of the DNA barcoding workflow at the Centre for Biodiversity Genomics (CBG). A newly designed imaging rig has enabled the CBG to quickly and efficiently image specimens at high quality while controlling the specimen’s orientation to emphasize key morphological characters. This system allowed the CBG to take some 190,000 images over the past year.
The SLR rig is placed on a heavy-base table to minimize vibration. The inset shows the actual rig area with specimens on the styrofoam base.
Our new ZooKeys study describes this imaging rig, which was mainly created for pinned specimens. It is inexpensive and easy to install as it uses a camera mounted to a CNC machine rig to photograph specimens at high capacity. By using a foam board to array specimens, the user can choose their orientation, which contrasts some existing methods that do not provide such flexibility. This setup produces 95 high quality images within half an hour.
Panel of example images taken with the SLR rig.
The flexibility of the imaging rig could benefit many potential users who are looking for an accessible method for larger collections of specimens. By alternating various parameters, such as the distance between the camera and specimens or the type of camera and lens used, users can adapt their system to specimens of varying sizes. With further changes to the array, the imaging rig can also be adapted to support imaging specimens on slides, within vials, or other storage solutions.
The proposed model of an entomological block is ready for printing on a standard 3D printer. In addition to the usual positioning of glue boards and labels along the Z-axis, the model also offers targeting devices that enable precise positioning of the entomological pin along the X- and Y-axes.
Dimensions of the entomological pinning block with metal rail.
The model is offered in two variants – one for immediate use after printing and another that requires the fabrication of an additional steel rail measuring 100 × 30 × 5 mm, against which the tip of the pin rests during positioning along the Z-axis. The rail is also used to increase the overall mass of the fixture. The overall dimensions of the device are 100 mm in length, 35 mm in width and 37 mm in height.
The proposed entomological block is intended for widespread use by entomologists, particularly those using insect glue boards. It is applicable to large entomological collections with individual specimen numbering and its use can ensure that entomological pins are positioned on the label so as not to disrupt the integrity of the number or barcode.

Over the last few years, professor Halil Ibrahimi from Kosovo and his team have described several new species of aquatic insects revered as bioindicators of freshwater ecosystems. However, the celebration of these discoveries is tempered by alarming concerns: the newfound species are often already considered endangered, as per the criteria set forth by the International Union for Conservation of Nature (IUCN), as soon as they are described. This classification underscores the urgent need for conservation efforts to safeguard their existence.
The research team just discovered a new species, named Potamophylax kosovaensis, in the spring area of the Llap River, nestled within the Ibër River Basin. The region, known for its ecological significance, serves as a critical habitat for numerous aquatic organisms like newly discovered insect species.

Unfortunately, these freshwater insects are facing unprecedented threats in Kosovo and the broader Balkans region. Anthropogenic pressures, such as water pollution, littering, and the construction of hydropower plants, pose imminent risks to their survival. The degradation of their habitats not only jeopardizes their existence, but also undermines the health and integrity of entire freshwater ecosystems.

Professor Ibrahimi emphasizes on the importance of urgent action to mitigate these threats and conserve this delicate balance of freshwater biodiversity. “The discovery of Potamophylax kosovaensis serves as a stark reminder of the fragility of our freshwater ecosystems,” he states. “We must prioritize efforts to protect these habitats and the invaluable species they harbor.”
