New research expands the knowledge on chalcid wasps in Cyprus, with five new species described from the island. One was named after the Greek goddess Aphrodite.
Scientists have described five new species of parasitoid wasp from Cyprus, more than doubling the number of chalcid wasps known to be found nowhere else on the island. The wasps, all belonging to the family Pteromalidae, are small insects that play an important role as natural pest controllers, yet remain poorly studied across much of Southeastern Europe and the Middle East.
“Before the start of this study, our knowledge regarding the chalcid wasp fauna of the Akrotiri Sovereign Base Area (SBA) and the rest of the island of Cyprus was extremely limited,” said Koutsoukos.
Chalcid wasps comprise a hyperdiverse group of insects that serve as biological controllers both in natural and manmade ecosystems, and as such it is crucial to enrich our knowledge, towards understanding their true extend of biodiversity, ecology, and their role in the various trophic webs they participate across different ecosystems.

“Each of the five new species was named with a story behind it. Two of the species [Ablaxia makrisi and Erythromalus makrisi] were named after Mr. Christodoulos Makris, prominent Cypriot entomologist, for his contributions on the Cypriot biodiversity, and for collecting the holotypes of these two species,” Koutsoukos explained.

Hemitrichus akrotiriensis takes its name from the Akrotiri peninsula, described by Koutsoukos as “a protected area and one the greatest biodiversity hotspots in Cyprus, where the holotype was also collected from.” Another species, Ablaxia toxeftrae, was named after Toxeftra beach in the Akamas peninsula, where its holotype was found.
The final species carries perhaps the most evocative name of all:
Janssoniella aphrodite was named after the Greek Ancient Goddess Aphroditi, since the holotype of this species was collected in Yeroskipou area of Paphos, where the Goddess was worshipped during ancient times.

Before this study, only three chalcid wasp species were known to be unique to Cyprus. “Our collecting efforts yielded many more interesting specimens, which might represent new species as well,” said Koutsoukos, “and as such it is evident that these numbers are an underestimation of the true biodiversity of the island.”
“The outcomes of this project will contribute towards the enrichment of our knowledge of the biodiversity, not only of the island of Cyprus and the U.K. SBAs, but the whole region’s as well,” Koutsoukos said.

The floodlights have dimmed, the confetti has settled, and the 2026 FIFA World Cup has officially come to an end. A huge congratulations to Spain, who saw off Argentina 1-0 after extra time to lift their second World Cup trophy.
And with the football finished, it’s time for us to blow the final whistle on our own tournament too. Throughout the World Cup, we ran the Pensoft Biodiversity Cup alongside the real competition – a weekly knockout contest on our Instagram page, pitting some of the most remarkable species described in our journals against one another.
Every Thursday we opened the polls, and every Monday we brought you the result. Now that the dust has settled, we thought it was the perfect moment to look back at how the tournament unfolded.
Here’s how each fixture played out, with the winning species (as voted for by you!) shown in blue bold:

General recap of Pensoft’s Biodiversity Cup.
Our first week’s competition kicked off with a cloud-forest chameleon named after Jane Goodall, which faced off against a public-named deep-sea chiton from the abyssal Pacific:
…and round two went to the fungi! Neohelicomyces coffeae ended up decisively defeating the jade ginger Hellwigia opalina in this Plant vs Fungi edition.
Round three brought Cave vs. Coast: a Balrog-named cave cricket unearthed on Kastellorizo faced a sesame-speckled nudibranch discovered off northeastern Taiwan:
Our third round went to the underdog (or in this case, undercricket): Dolichopoda balrogi, which hopped past Thecacera sesama in a unanimous win.
Round four was our Animal Kingdom edition, with the newly described Pink Floyd spider Pikelinia floydmuraria facing off against the burrowing snake Trachischium lalremsangai for the top spot:
Pikelinia floydmuraria vs Trachischium lalremsangai.
The snake slithered through – Trachischium lalremsangai defeated Pikelinia floydmuraria, its burrowing lifestyle proving harder to top than a rock-star spider name in this round.
Our second-to-last round paired the smiley-faced Himalayan Happy-Face Spider, Theridion himalayana, against Pyralis papaleonei, a papal-named moth endemic to Crete’s White Mountains:
The moth flew past the competition! Pyralis papaleonei took the win over Theridion himalayana, its rare papal namesake and striking wing bands proving enough to edge out even a face full of smiles.
Our own final on 19 July ended up mirroring the World Cup final to a tee, with a species from Spain going head-to-head with one from Argentina:
Representing Spain in the final was Iberoscia zaragozai, a newly described genus and species of cave-dwelling isopod, published only this April in our open-access journal Subterranean Biology.
Discovered in caves across Catalonia, Murcia and the Valencian Community, this blind crustacean measures barely 3-4 mm long, yet required a new genus to accommodate it, thanks to its unique features – right down to its antennal sensory structures.
Fittingly, it’s named in posthumous tribute to the Spanish arachnologist Juan Antonio Zaragoza-Miralles, in recognition of his decades of work on the cave-dwelling fauna of the Iberian Peninsula.
Standing in Argentina’s corner was Echinodorus nenufar, a new aquatic plant described in PhytoKeysback in January. Found in the temporary ponds and seasonal wetlands of the dry Chaco region of northern Argentina and western Paraguay, it earns its name – “nenúfar” being Spanish for water lily – thanks to its rounded floating leaves and creamy-white flowers, which give it an uncanny resemblance to a true Nymphaeaceae water lily.
Like the seasonal killifish it shares its ephemeral ponds with, it has evolved to complete its whole life cycle in habitats that can appear and vanish with the rains.
Two species, two countries, both barely a few months old to science. This is a proper final if ever there was one. And… just like their footballing counterparts, it was the Spanish contender that came out on top!
We had an absolute blast running the Biodiversity Cup alongside this year’s World Cup, and we hope it gave you a fun new way to discover some of the incredible species being described in our journals. Thank you to everyone who voted, shared and cheered along from the side lines.
The new species, which was described based on morphological characteristics and DNA barcoding from worker, gyne and male castes, brings the total number of Messor species known from Bulgaria to nine.
An international team of researchers has announced the discovery of a new species of harvester ant, officially named Messor odrysarum. The discovery was made by researchers Albena Lapeva-Gjonova of Sofia University in Bulgaria and Lech Borowiec of the University of Wrocław in Poland.
The findings were recently published in the scientific journal ZooKeysand bring the total number of recognized Messor ant species in Bulgaria to nine.

The newly identified ant is part of the Messor genus, a group well-known for their ecological role as grain and seed collectors in arid and semi-arid environments. The researchers chose the specific name “odrysarum” to honor the ancient Thracian state of Odrysia (roughly founded in early 5th century BC), whose historical geographical borders included the region where this new species was found.
Habitat and Behavior

Messor odrysarum is a lowland species that has been documented at elevations up to 647 meters in the Eastern Rhodopes region of Bulgaria. Researchers discovered their nests situated along dirt roads within oak forests and open grasslands. The nest entrances are built at ground level and “in late summer, seed remains were observed near the nest entrances”.
Messor odrysarum sp. nov. is currently only known from the Eastern Rhodopes in Bulgaria, possibly also occurring in the Thracian region of Greece and Türkiye.
explain the researchers in their article.
Distinct Physical Characteristics

Confirmed through both rigorous morphological analysis and modern COI DNA barcoding, Messor odrysarum belongs to the Messor structor species group. While it is closely related to the known Balkan-Anatolian species Messor oertzeni, there are several distinctive physical traits that make the newly discovered ant stand out.
It has a smaller overall body size compared to its close relatives and it is accented only by reddish hues on the lower genae (the cheek region of the head). It also has a narrowed head behind the eyes, longer and denser hairs (setae) on its head and midsection, and a longer antennal scape.
Scientific Significance
The formal description of Messor odrysarum helps to resolve ongoing taxonomic complexities within the Messor genus, which is known for cryptic diversity and remarkable reproductive strategies like hybridization or even xenoparity, where female gives birth to, or clones, offspring of a completely different species as part of its lifecycle.
In addition to introducing the new species, the researchers’ publication also provides a rare, updated redescription of the queen (gyne) caste of the related M. oertzeni based on newly collected specimens.

A research team from the Natural History Museum of Denmark has published a compelling new study in insect taxonomy in the open-access journal ZooKeys, officially establishing a new genus of rove beetle (Staphylinina): Luffy gen. nov. The inspiration for the name comes directly from Monkey D. Luffy, the iconic protagonist of the globally popular manga and anime One Piece.
Why Name a Beetle Genus “Luffy”?
The research team noted that naming the new genus Luffy was not merely for fun, but rather a direct reflection of the beetles’ highly recognizable morphological characteristics.

The species within this genus possess mandibles, antennae, and maxillary palps that are significantly longer and more slender than those of closely related groups. This uniquely elongated overall proportion immediately reminded researchers of Luffy’s rubber body abilities in One Piece, which allow him to freely stretch and expand.
Two New Beetles in the New Genus
Currently, two distinct species have been discovered and classified under this new genus: Luffy schillhammeri and Luffy nika.
The species Luffy schillhammeri was found in the broadleaf forests of Yunnan Province, China. The specific epithet of Luffy schillhammeri honors Dr. Harald Schillhammer of the Natural History Museum Vienna, recognizing his long-term and outstanding contributions to the research of rove beetles.

Luffy nika was discovered in Louang Namtha, northern Laos. The specific epithet “nika” originates from Luffy’s legendary Devil Fruit awakening, “Hito Hito no Mi, Model: Nika” (also known as Gear 5). This new species features striking white band-like hairs on its elytra and across much of its body, closely resembling Luffy’s classic, all-white, smoke-shrouded appearance during his Nika transformation.

Major Scientific Breakthrough: Filling a Key Evolutionary Gap in the Eucibdelus Lineage
Beyond its eye-catching name, this study holds high scientific value. The research team, consisting of PhD student Fang-Shuo Hu and Alexey Solodovnikov from the Natural History Museum of Denmark, systematically reviewed all known genera of the Ocypus-group.
They also included several groups whose taxonomic positions had long been questionable and controversial (such as Acupronotes, Apostenolinus, and Staphylinus). Through the examination of a large number of specimens and rigorous comparisons of subtle morphological features, the team successfully re-evaluated the phylogenetic relationships among these groups and put forward key findings.
Diversity of labrum morphology of Ocypus-group and Staphylinus. A. Luffy; B. Agelosus; C. Cyanocypus; D. Protocypus; E. Ocypus; F. Eucibdelus; G. Guillaumius; H. Menoedius; I. Parapalaestrinus; J. Paraphytolinus; K. Rhynchocheilus; L. Rhyncocheilus; M. Trichocosmetes; N. Staphylinus.
The research team clearly identified the synapomorphies of the “Eucibdelus lineage” (such as the left mandible possessing dorsal ridge teeth and a completely sclerotized labrum). Interestingly, while the genus Luffy possesses these dorsal ridge teeth, its labrum is not completely sclerotized, and it carries several distinct traits of its own.
Based on this morphological evidence, the research team infers that the genus Luffy is highly likely to be the sister group to the entire Eucibdelus lineage. Highlighting that our understanding of this insect lineage is continuously evolving with new discoveries, the researchers note:
This genus exhibits a unique combination of characters intermediate between the Eucibdelus lineage and other members of the Ocypus-group.

This discovery successfully fills an important gap in the existing taxonomic framework, providing a new perspective on the evolutionary history of the subtribe Staphylinina.
Inspiring the Next Generation of Scientists
From manga inspiration to publication in a rigorous international scientific journal, the birth of the genus Luffy proves that scientific research can be both serious and highly engaging. The research team looks forward to closing the distance between science and the general public through such an accessible story, raising awareness about the importance of biological taxonomy, and attracting more of the younger generation to dive into biodiversity and taxonomic research with an adventurous spirit just like Luffy’s.

The Pikelinia floydmuraria, a new addition to the South American Pikelinia population, was observed in Colombia’s department of Tolima and is now described in the journal Zoosystematics and Evolution.
A team of researchers from institutions across South America have expanded scholarly knowledge of the Pikelinia spider genus, with their recent discovery of a new crevice weaver species: Pikelinia floydmuraria.
The new species name is a creative tribute to the legendary rock band Pink Floyd, while simultaneously referencing the spider’s specific habitat. “Muraria,” derived from the Latin word for “wall”, reflects the species’ tendency to reside in the walls of buildings, though indeed also alludes to the iconic Pink Floyd album, The Wall.

These findings are described in greater detail in the open-access journal Zoosystematics and Evolution (ZSE) and serve as a particularly important contribution to the wider study of synanthropic spiders – species that have adapted to human-created environments. Despite the ecological importance of these spiders in Colombia, research into their biology and nutritional ecology has received little attention. The discovery of the Pikeliniafloydmuraria, alongside observations of additional populations in neighbouring Colombian departments, holds the potential to remedy this problem.
The species establishment
The first regional review of the genus Pikelinia was established in 1946 by the Brazilian zoologist Mello-Leitão. For decades, the genus remained obscure, with species often misidentified or “lumped” into the type genus Filistata, most commonly found in the Mediterranean region.
In 2022, however, a major study redefined Pikelinia as part of a distinct South American spider group. Pikelinia floydmuraria is the most recent addition to the genus and provides considerable insight into the dietary composition of these crevice weavers.

These spiders are skilled hunters, primarily feeding on insects including flies, beetles and ants. Remarkably, they are capable of taking down prey up to six times their own size and often build their webs near streetlights to catch insects attracted to the glow. The above figure provides a visual representation of the spider’s predatory behaviour in urban habitats, demonstrating its ability to prey on insects larger than itself.By keeping these insect populations under control, crevice weavers thus maintain a healthier balance in the Colombian urban environment.
The research team behind this discovery, led by Osvaldo Villarreal and Leonardo Delgado-Santa, note that Pikelinia floydmuraria only measure about 3 to 4 millimetres in length. One of their most unique internal features is found in the females, which contain reproductive organs comprising long and slender tubes that are shaped like the letter “S”. In urban environments, they can be found tucked in the cracks and crevices of building walls, with observed concentrations reaching between 20 and 30 spiders in a single square metre.

The researchers further observed that Pikelinia floydmuraria is a very close relative of another species called Pikelinia fasciata, which lives in the Galapagos Islands. Despite being separated by the Pacific Ocean and Andes mountain range, the two look almost exactly alike, leaving scientists to wonder: how did such similar spiders end up so far apart? It remains a mystery as to whether these traits reflect shared ancestry or similar ecological adaptations.
Nonetheless, the two can be differentiated by the appearance of their legs, with the Colombian spider displaying solid-colours, and the Galapagos featuring darker rings by contrast. The Galapagos female spiders additionally have shorter and straighter reproductive organs in comparison to the Colombian female.
🎸🕸️ Meet the latest rock star of the #spider world: Pikelinia floydmuraria. 🕷️Recently discovered in Colombia, this species was officially named after @Pink Floyd as a tribute to both their iconic album “The Wall” and the spider’s favourite hangout: urban city walls. ➡️ Follow the link to read more about this discovery: https://zse.pensoft.net/article/175423/ ➡️Or see the blog post here: https://blog.pensoft.net/2026/04/14/meet-the-crevice-weaver-a-newly-discovered-urban-spider-from-colombia/ #arachnid#spiders#newspecies#science
In order to better determine whether Pikelinia floydmuraria is a unique species native to Colombia, the South American researchers suggest the implementation of DNA barcoding in future studies. This will provide genetic evidence that could help map the evolutionary history of Pikelinia floydmuraria. A DNA-based dietary analysis, meanwhile, would quantify the extent to which these spiders operate as natural urban pest regulators.
Whether they are just “another web in the wall” or a relative from the Galapagos, the discovery of Pikelinia floydmuraria represents a significant advancement in our understanding of South American spider taxonomy. By identifying this new Colombian species and providing the first-ever detailed anatomical description for its relative, Pikelinia fasciata, researchers have expanded scientific knowledge of the Pikelinia genus.
Pikelinia floydmuraria may be small and “comfortably numb” to the bustle of the city, but their impact on maintaining a healthy urban ecosystem is anything but quiet.

In the canopies of a South American rainforest, a tiny soldier termite has stunned a team of international scientists with its whale-like features.
Cryptotermes mobydicki, the name given to the termite by the international research team — led by a University of Florida scientist — boasts features of an elongated head and hidden mandibles. It resembles the iconic sperm whale from Herman Melville’s classic novel — hence its name.
These slides show views of the termite soldier’s frontal prominence and elongated head resembling the head of a sperm whale, and how in both the whale and termite, the mandibles are eclipsed by the head. Photo provided by Rudolph Scheffrahn.
“This termite is unlike anything we’ve ever seen,” said Rudolf Scheffrahn, professor of entomology at the UF Institute of Food and Agricultural Sciences (UF/IFAS).
The specimen was so distinctive that the team of international entomologists thought it was looking at specimens of an entirely new genus, said Scheffrahn, whose taxonomic research is based at the UF/IFAS Fort Lauderdale Research and Education Center.
This termite is unlike anything we’ve ever seen
Rudolf Scheffrahn
“The lateral view of the soldier’s frontal prominence and elongated head resembles the head of a sperm whale, and in both organisms, the mandibles are eclipsed by the head,” he said. “The whale’s eye and soldier’s antennal socket are comparatively positioned. After I noticed the resemblance to a sperm whale, my coauthors thought the name to be appropriate and whimsical, much like ‘ghost orchid’ or ‘Dumbo octopus.’”
The discovery adds a 16th species to the South American roster of Cryptotermes termites. A genetic family tree analysis shows that Cryptotermes mobydicki is closely related to other neotropical species found in Colombia, Trinidad and the Dominican Republic, giving scientists a new clue into the evolutionary story of this globally distributed genus.
Illustration from an early edition of Moby-Dick.
Researchers found the colony in a dead, standing tree about eight meters off the forest floor. It’s unusual anatomy highlights the diversity of termite evolution and the surprises still waiting in tropical ecosystems.
“The discovery of this distinctive new termite species underscores the vast number of unnamed organisms yet to be discovered on our planet,” said Scheffrahn.
To scientists, discovery is also a win for biodiversity. Every new species discovered adds to scientific understanding of life on earth, especially in a group as small as termites with only about 3,000 species worldwide.
There is also good news for Florida property owners. As a newly described drywood termite species, Cryptotermes mobydicki is no threat to homes or trade. Unlike other invasive termites that cause costly damage in parts of the southeastern United States, this species is found only in its rainforest habitat and does not spread beyond it.

Following a fantastic week in Portland at both ECN 2025 and Entomology 2025, Pensoft looks forward to continuing its close collaboration with the entomological and collections communities. The Entomological Society of America’s next annual meeting, Entomology 2026, will take place on 8–11 November in Columbus, Ohio, where Pensoft plans to create more partnerships and continue its support for open science in insect research.
This issue brings together novel research from contributors worldwide, covering taxonomy, morphology, ecology, pest management, and historical perspectives.
Guest blog post by Caroline S. Chaboo, Yoko Matsumura, and Michael Schmitt
We are thrilled to announce the publication of the 10th volume of Research on Chrysomelidae (RoC10), which appeared in September 2025. It was born at the 11th International Symposium on the Chrysomelidae that occurred during the 27th International Congress of Entomology (ICE) in Kyoto, Japan, August 2024. This volume continues the legacy begun in 2008 by Pierre Jolivet (1922–2020), whose vision launched the RoC series. Since RoC3, Pensoft Publishers have been a wonderful partner to prepare and publish these special issues in ZooKeys.
Returning to Japan after 44 years, ICE Kyoto was the largest entomological event since the pandemic, drawing over 4,000 participants—more than 1,000 from Japan. The symposium particularly offered young Japanese researchers a rare opportunity to engage with global experts, in our shared passion for the spectacular leaf beetle family.

RoC10 brings together novel research in biology and systematics from contributors worldwide. The volume comprises scientific papers and historical articles. Authors are emerging students, seasoned experts, and interdisciplinary teams. Topics cover taxonomy, morphology, ecology, pest management, and historical perspectives.
After co-editing 12 volumes—including 10 RoC editions—Michael Schmitt steps down from the editorial board. He passes the torch to new and younger colleagues to continue this tradition that began in 1985. We owe much gratitude for his impressive contributions and we welcome new researchers to join us at the 13th European Congress of Entomology in Tours, France (July 2026), and the 28th ICE in Cape Town, South Africa (July 2028). Let’s keep this vibrant momentum going!
With the Grassland Butterfly Index for Germany, UFZ scientists are providing important input for the implementation of the EU Nature Restoration Regulation.
One of the goals of the EU Nature Restoration Regulation, which came into force in 2024, is to halt species loss and preserve important ecosystem services provided by agricultural landscapes.
The results, published in the open-access journal Nature Conservation, show a negative trend, especially in recent years. For their calculations, the researchers were able to draw on 4 million observation data collected at the UFZ over the last 20 years as part of the ‘Butterfly Monitoring Germany’ programme.
Agricultural landscapes are among the most degraded habitats worldwide. Their restoration is one of the key measures for halting global biodiversity loss and preserving important ecosystem services.
“The Nature Restoration Regulation (NRR), which came into force in 2024, is an essential instrument for achieving the restoration targets set for the European Union,” says Prof. Josef Settele, agroecologist at the UFZ. The objectives also include increasing biodiversity in agricultural ecosystems (Article 11 of the NRR), taking into account climate change, the needs of rural areas and sustainable agricultural production. To implement the overall objectives, EU Member States are required to develop national restoration plans and implement concrete measures in terrestrial, freshwater, coastal and marine habitats.
The extent to which the specific measures are effective and the ecosystems develop positively will be determined using indicators. For agricultural landscapes, these are (a) the grassland butterfly index, (b) the stock of organic carbon in cropland mineral soils, and (c) the share of agricultural land with high diversity landscape features. For at least two of these three indicators, the EU regulation calls for an upward trend towards a satisfactory level by 2030. Since natural conditions vary across EU countries and there is a wide range of different land management practices, Josef Settele argues that all EU countries should start by recording all three indicators so that none of them is prematurely dropped.
With the ‘Grassland Butterfly Index’, a research team led by the UFZ has now calculated one of the three indicators for Germany for the first time and published the results in the journal Nature Conservation. The data for this analysis comes from Butterfly Monitoring Germany (Tagfalter-Monitoring Deutschland – TMD), a long-term programme coordinated by the UFZ and the Society for Butterfly Conservation (GfS). Every week during the summer, volunteers count butterflies at fixed locations using a standardised European method.
“Since the TMD was launched in 2005, this has resulted in around four million data records being collected, which provide information on the development of butterfly populations in Germany,” explains one of the co-authors of the publication, biologist Elisabeth Kühn, who coordinates the German Butterfly Monitoring programme at the UFZ.
What does the index show for Germany?
The ‘Grassland Butterfly Index’ tracks the development of populations of 15 butterfly species from 2006 to 2023 that are considered typical inhabitants of various grassland biotopes.
“Four species have increased, five species show a declining trend. For six species, the trend is uncertain, which is probably due to insufficient data and large differences between the locations where they were found,” says the study’s lead author, bioinformatician Alexander Harpke. In the first decade of the period analysed (2006 to 2016), the index for Germany as a whole shows a slightly positive trend – which does not rule out the possibility that this may vary greatly for individual species.
However, if we look only at recent years (2016 to 2023), the index shows a significant decline overall. This mainly affects specialised species such as the Small Blue (Cupido minimus) or the Dingy Skipper (Erynnis tages); generalists such as the Small Copper (Lycaena phlaeas) or the Meadow Brown (Maniola jurtina) are hardly affected.
These results show that the trend for grassland butterflies in Germany during the comparison period corresponds to the trend at European level, which was last determined by Butterfly Conservation Europe in 2025 for all 27 member states.
Butterflies are known to be sensitive to changes in their environment. Land use plays a decisive role in this. “The loss and fragmentation of habitats have a proven negative effect on the long-term survival of butterfly populations. Intensive mowing, nitrogen inputs and pesticides contribute to a deterioration in habitat quality or increased mortality. Species that depend on specific habitats, such as nutrient-poor grasslands, also suffer from a lack of use, e.g. through grazing or mowing,” explains Prof. Thomas Schmitt from the Senckenberg German Entomological Institute (SDEI) in Müncheberg, who is also co-author of the study.
In addition to land use, climate change is increasingly contributing to changes in butterfly fauna. Higher temperatures favour the spread of heat-loving or tolerant species, while species adapted to cooler conditions are in decline.
These dependencies of butterflies on land use and climate change make them excellent indicators of the state of our ecosystems. In addition, they are easy to record – especially by qualified volunteers. Together, these two factors have provided an invaluable database for butterfly monitoring in Germany, which scientists are now evaluating to calculate trends and indicators for reporting under European environmental legislation.
“The significance and representativeness of the indicator could be further increased if government programmes such as Habitats Directive monitoring or nationwide insect monitoring were integrated into the analysis,” says UFZ biologist and co-author of the publication Dr Martin Musche. The same would apply if data from neighbouring countries were included.
The collection brings together contributions from faculty, curators, collection managers, and students from around the world, having sprung from the November 2024 “Collections Reaching Out” symposium at the Entomological Collections Network annual meeting in Phoenix, Arizona. The symposium focused on the conception, preparation, management, and educational use of outreach drawers: special collections of insect specimens curated for public learning and awareness.

Despite their crucial role in science education and public engagement, outreach drawers have remained understudied. The papers in this new collection aim to fill that gap, examining their purpose, design, usage, and how to assess their impact. The editors, Victor Gonzalez and Jennifer C. Girón Duque, brought together international perspectives to identify best practices and strategies that maximise outreach effectiveness.

By exploring topics from innovative educational programs and accessible specimen displays, to community science initiatives and frameworks for assessment, the collection demonstrates how outreach collections can turn “bugs in drawers” into powerful vehicles for learning and community engagement.
NHCM’s Diamond Open Access model ensures that these resources are free and available to all, reaffirming the journal’s commitment to inclusivity and expanding the societal impact of natural history collections.
