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.

This new study not only presents new records of bee species in Serbia and confirms some old ones, but also provides additional information about European distribution.
Pollinators play a crucial role in our ecosystems by pollinating flowering plants and crops, contributing to the planetary and human well-being. During the past decade, the decline in insect pollinators has become a more and more disturbing issue that countless scientific and public communities are trying to tackle every day.
Published in the Journal of Hymenoptera Research, a new study aims to contribute to updating the knowledge on wild bee diversity in Serbia, necessary for determining conservation priorities and future endeavours at the national level, but also for improving the understanding of the status of European pollinators. The study is also making an attempt to upgrade the exciting data provided by the recently published checklist of European bees, European bees country records, and, focusing on Serbia, a preliminary list of 706 bee species.
Map of Serbia showing the localities where bee specimens were collected.
To do that, researchers used data from the implementation of the national project SPAS, and within the EU-funded project Safeguard. With the aim of monitoring the diversity and abundance of insect pollinators in Serbia, 54 sites were surveyed three times throughout the 2022 season.
The transect walks and pan traps used for the assessment led to the discovery of 312 bee species. Results show that 25 of these have not been previously recorded for Serbia. Furthermore, the study confirms the presence of 26 species, without any available records from the 21st century.
Graphic view of the number of species detected depending on the sampling methods A at all studied sites B at a subset of sites where both sampling methods were conducted.
The authors also share that 79 of the examined species were known only from literature-based data and six of the recorded species are considered threatened with 67 (10 newly recorded) assessed as Data Deficient in the European Red List of Bees. In addition, the study manages to achieve the goal of updating the current knowledge of bee species occurring in Serbia. By recording 25 new species, the Safeguard study successfully extends the national list with new recordings – from 706 to 731 species.
This new study not only presents new records of bee species in Serbia and confirms some old ones, but also provides additional information about European distribution, required for new assessment at the European level.

Jewel wasps (Chalcidoidea) are one of the most diverse groups of insects, with more than 120,000 species described and an estimated true diversity of nearly one million. The chalcids are parasitoid wasps, which attack other insects to lay their eggs upon in order to feed and grow within the host. The evolution and origin of this immense group has puzzled scientists for decades. Based on fossils and molecular work, the group is thought to have originated in the late Jurassic around 162 million years ago. Until recently, no confirmed fossils were known from earlier than 100 million years ago. Now, a newly described family, Protoidae, provides the first glimpse into how these wasps appeared at the earliest stages of their evolution.
Protoita noyesi.
Scientists Jonah M. Ulmer, Dr. Petr Janšta, and Prof. Dr. Lars Krogmann, from SMNS – State Museum of Natural History Stuttgart, alongside Dr. Dany Azar from the Lebanese University describe the new family and 10 new species of jewel wasps in a paper in the open-access Journal of Hymenoptera Research.
The discovery of the family came about when one of the coauthors, Prof. Dr. Lars Krogmann, noticed an unusual fossil during a visit to the Natural History Museum in Paris. The specimen embedded in the amber had a long tail-like structure covering its ovipositor. “It was previously described as a completely different type of wasp, however the authors were quick to recognize it was indeed an ancient chalcid. Despite the prevalence of Chalcidoidea in the fossil record, none had ever been recorded from Lebanon or were known to be that old, nearly 130 million years old to be exact,” says Jonah Ulmer.
Cretaxenomerus brevis.
The researchers soon realized they had a new, and very old, family: currently the oldest known within the jewel wasps. “Multiple similar specimens in amber soon became apparent and the family now contains two genera, Protoita and Cretaxenomerus. The family name is derived from being a ‘proto’ form of the Chalcidoidea,” Ulmer explains.
These ancient species present a unique snapshot of what these wasps looked like in their earliest forms, this allows researchers to better understand the order of evolutionary events through time and when certain structures evolved that ultimately led to the massive diversity we see today.
Cretaxenomerus curvus.
The new family’s most striking characteristic is the long, shovel-like process, which extends from the end of the abdomen. While no living species have such a pronounced structure, it is hypothesized to have assisted with egg-laying and ovipositing or perhaps sifting through loose leaf litter for hosts.
The authors note that there are likely other equally old families of Chalcidoidea still lying in wait to be discovered, either in the ground or in old forgotten museum cabinets. “Protoitidae shows that we can keep looking further back in time than we expected and still find new, and old, species” says Ulmer.

Guest blog post by Yu Hisasue, Kazuhiko Konishi, and Kenji Takashino
Parasitoid wasps have developed behaviors to adapt to the ecology of various hosts and overcome their means of avoiding parasitism. Host searching behavior is a crucial stage for parasitoids, not only for efficient host search, but also for competing with other parasitoids that exploit the same host as a resource. A variety of such behaviors has been reported, including utilizing chemical or sonic cues. Parasitoid wasps select their strategies based on their own morphology, their host, and the host’s habitat.
Parasitoid wasps that challenge the ant society are known to have highly specialized morphologies and behaviors.
Female of Ghilaromma orientalis hanging from the grass above the ant trail with her head facing the trail.
All members of the subfamily Hybrizontinae are ant parasitoids, and specialize to the ant society, representing the third most diverse group of ant parasitoid wasps after Eucharitidae and Neoneurini. The oviposition behavior has been reported for three species belonging to three different genera in Hybrizontinae: Ogkosoma cremieri, Neohybrizon mutus, and Hybrizon buccatus. In these species, the females hover over an ant trail, and when they come across ant larvae carried by workers, they attack and lay eggs on the ant larvae.
No reports have been made for oviposition behavior in the genus Ghilaromma. G. orientalis was suggested to be a specialist of Lasius nipponensis, but its oviposition behavior was unknown.
Female Ghilaromma orientalis using her front legs to contact an ant larva and directing her abdomen towards it, while maintaining a firm grip on the grass with her hind legs.
In our ten years of frantic observation, we were fortunate enough to observe the parasitic behavior of G. orientalis a single time. On 20 October 2015, Kenji Takashino observed the oviposition and took pictures of it on his phone.
He noticed that the female, hung on the grass growing along the ants’ trail on its hind legs with its head down, and when workers with larvae pass by, stretched its abdomen toward the larvae with its hind legs remaining on the grass.
Female Ghilaromma orientalis maintaining a firm grip on the grass with her hind legs while adjusting her body position to oviposition onto a larva being carried away by an ant.
There are different merits and demerits of the two strategies in Hybrizontinae. The active type has the advantage of covering a wider search area and enabling the movement of the parasitoid to areas where the ants carrying larvae are located. However, this strategy has the drawback that hovering of parasitoid wasps over an ant trail alerts the ants and prevents larva-carrying ants from exiting the nest entrance or covered area. In addition, ants have been observed to open their mandibles to threaten hovering wasps, which then occasionally fail to fly or get captured by worker ants.
Workers of Lasius nipponensis with their mandibles open, alerted to the hovering Ogkosoma cremieri.
The ambush type has the limitation of a narrow search area. As ant larvae are not always conveniently transported by workers close to the wasp, narrowing the search area directly leads to a decrease in parasitic opportunities. However, the ambush type strategy affords G. orientalis the advantage of laying eggs without being noticed by ants and in a narrow environment where wasps cannot fly in active type.
In addition, we report a new host ant (Lasius cf. fuliginosus) for G. orientalis. Some members of this species group are known to transport their larvae outside the nest. Therefore, it is plausible that G. orientalis may use not only a single ant species, but multiple L. fuliginosus-group species that have a habit of transporting larvae outside the nest.
Although we made only one observation of the wasp, we compared and discussed the other ecological information and parasitic behavior of closely related species using observations, literature, and studies on the parasitic behavior of other well-studied parasitoid wasps.

MINNEAPOLIS/ST. PAUL (05/11/2023) — Researchers at the University of Minnesota have discovered a new species of tiny parasitic wasp that might prove beneficial to managing soybean gall midge, a recently emerged pest in Midwest soybean fields that can have devastating impacts on plant production.

Since the appearance of the midge in 2018, growers have struggled to manage this insect, prompting researchers to seek effective and environmentally-friendly ways to help soybean farmers protect their crop. One approach is biological control, using natural enemies to kill pests. However, because soybean gall midge is new, very little is known about which species might prove to be good allies to growers in the fight against this damaging insect.
Amelia Lindsey, an assistant professor in the Department of Entomology, and Robert Koch, an associate professor in the Department of Entomology and an Extension entomologist, led the team at the University of Minnesota. They focused on searching for parasitoids — insects that lay their eggs in or on another insect — of soybean gall midge. Juveniles of the parasitoid develop inside the other insect, eventually killing them.
To find such parasitic insects, a graduate student in the Lindsey and Koch labs, Gloria Melotto, collected soybean gall midge-infested plants from a Minnesota farm and waited to see which adult insects emerged from the plants.
The researchers found:
In addition to a lot of soybean gall midges, there were a number of tiny parasitoid wasps.
In collaboration with two taxonomists who specialize in this group of insects—Jessica Awad, doctoral researcher, State Museum of Natural History Stuttgart, and Elijah Talamas, Florida Department of Agriculture and Consumer Services—it became clear that there was no information on this wasp anywhere in the scientific record. It is a new-to-science species.
The team used DNA sequencing data and physical characteristics of the wasps to formally describe the specimens and give them a scientific name: Synopeas maximum.
The findings point toward this newly described parasitoid wasp species being a likely natural enemy of soybean gall midge.
The head of Synopeas maximum.
“Unidentified and undescribed parasitoid micro-wasps are all around us. Although they are tiny, they play a huge role in regulating the populations of other insects, including pests. It’s really exciting to discover a new parasitoid species in such an important crop system,” said Awad.
“Effective management of soybean gall midge has proven challenging. Identification of a new species of parasitic wasp attacking this pest is an exciting breakthrough,” said Koch.
Ongoing work from the team includes a deeper dive into the biology of the wasp and the soybean gall midge to see how often this wasp attacks the pest, and how widespread this potential beneficial insect is across the midwest. Ultimately, the goal is to develop strategies for incorporating the natural enemy into management plans for safe and effective control of soybean gall midge infestations.
This research was supported by the Minnesota Rapid Agricultural Response Fund.
Another year rolled by and we at Pensoft have a lot to celebrate! This year, we marked our 30th birthday, and what a ride it’s been! We thank all of you for sticking around and helping us put biodiversity science in the spotlight where it deserves to be.
The holiday season is always great fun, but for us, every biodiversity or conservation win is reason enough to celebrate. And we’ve had so many this year! We already showed you our top species for the first half of 2022. Here’s an update for the second half with the most exciting new species that we’ve published across our journals:
The elusive owl from a remote island
The Principe scops-owl (Otus bikegila) was discovered on the small island of Príncipe, just off Africa’s western coast. Its existence had been suspected since 1998, but locals said its presence on the island could be traced back to 1928.
The bird is endemic to the island of Príncipe. Furthermore, the research team behind its discovery noted that it can be found only in the remaining old-growth native forest on the island, in an area that largely remains uninhabited.
8/9 The discovery and the subsequent scientific description were the result of a long process requiring the contribution of many people. It was a privilege to be a part of this.

Otus is the generic name given to a group of small owls sharing a common history, commonly called scops-owls. They are found across Eurasia and Africa, and include such widespread species as the Eurasian scops-owl (Otus scops) and the African scops-owl (Otus senegalensis).
The species epithet “bikegila”, in turn, was chosen in homage of Ceciliano do Bom Jesus, nicknamed Bikegila – a former parrot harvester from Príncipe Island and now a park ranger on the island.The new species quickly became insanely popular, generating memes (a true sign of its popularity!). One website even described it as “a flying meme-generator that sounds like a newborn puppy.”
Nepenthes pudicais a carnivorous plant that grows prey-trapping contraptions underground, feeding off subterranean creatures such as worms, larvae and beetles.
It belongs to pitcher plants – a group of carnivorous plants with modified leaves (called pitfall traps or pitchers) that help them catch their prey.
Pitcher plants usually produce pitfall traps above ground at the surface of the soil or on trees. N. pudica is the first pitcher plant known to catch its prey underground.
At first, the researchers thought the deformed pitcher protruding from the soil that they saw had accidentally been buried. Only later, when they found additional pitcherless plants, did they consider the possibility that the pitchers might be buried in the soil.
Then, as one of the researchers was taking photos, he tore some moss off the base of a tree and found a handful of pitchers.
The unique plant, however, could already be under threat. As it only lives in one small area of Indonesia, scientists believe it should be classed as Critically Endangered.
In November 2021, biologist Alejandro Arteaga and his colleagues were traveling through the cloud forests of Ecuador looking for toads, when a local woman told them she had seen odd snakes slithering around a graveyard. Based on her description, the team suspected they might be ground snakes from the genus Atractus, which had never been scientifically recorded in that area of Ecuador.
Indeed, they were able to discover three new snake species living beneath graves and churches in remote towns in the Andes mountains.
The “small, cylindrical, and rather archaic-looking” snakes all belong to a group called ground snakes. In general, not a lot of people are familiar with ground snakes, as they usually remain hidden underground.
Sometimes life gives you lemons, and sometimes you go looking for frogs and end up finding three new species of snake! In this episode we hear from Alejandro Arteaga about his new species from the Ecuadorian Andes.https://t.co/1YjQXSNJcJpic.twitter.com/8IKJGc2sCI
All three snakes were named in honor of institutions or people supporting the exploration and conservation of remote cloud forests in the tropics. Atractus zgap, pictured here, was named in honor of theZoological Society for the Conservation of Species and Populations (ZGAP), a program seeking to conserve unknown but highly endangered species and their natural habitats throughout the world.
However, the majority of the native habitat of these new snakes has already been destroyed. As a result of the retreating forest line, the ground snakes find themselves in the need to take refuge in spaces used by humans (both dead and alive), where they usually end up being killed on sight.
Unlike some other participants in this list, this one took a while before it was confirmed as a new species: “We did not discover that it was a new species overnight,” says Oscar Lasso-Alcalá, one of the people behind its discovery.
A. mikoljii is a new species for science, but it is not a “new species” for people who already knew it locally under the name of Pavona, Vieja, or Cupaneca in Venezuela or Pavo Real, Carabazú, Mojarra and Mojarra Negra in Colombia. Nor for the aquarium trade, where it is highly appreciated and has been known by the common name of Oscar.
Moreover, the species has been of great food importance for thousands of years for at least nine indigenous ethnic groups, and for more than 500 years to the hundreds of human communities of locals who inhabit the Orinoco River basin in Venezuela and Colombia. In the plains of Orinoco, it is considered a delicacy “due to its pleasant taste and enhanced texture”.
Oscar Lasso-Alcalá has a special relationship with this fish. “It is more than just a fish in an aquarium since it is considered a true pet,” he says.
Recently, Javier Lobon-Rovira, one of the people behind the discovery of this new gecko, told us what it was like to find this exciting new species: “That night we were tired, so we decided to have a short walk around the camp. And… there it was…! Like a ghost, this small, cryptic, and elusive gecko started showing up in every big rock boulder.”
Kolekanos spinicaudusis part of Kolekanos, a unique and iconic gecko genus that is only known from southwestern Angola.
Until this discovery, Kolekanos only had one species in the genus, known only from ~200km south of the new discovery, but that species had feathers on its tail, not spines like K. spinicaudus. Immediately, the researchers knew they were dealing with a Kolekanos… but they were astonished to see the spines.
GECKO SUNDAY! Another #NewSpecies of #gecko for 2022! Meet: Kolekanos spinicaudus • A new Feather-tailed Leaf-toed Gecko, Kolekanos (Squamata: Gekkonidae) from the poorly explored Savannah of western Angola 2022. link/summary: https://t.co/TWhm0JGhcypic.twitter.com/Z8wcug7IIt
The scientific name “spinicaudus” refers to the unique appearance of the tail of this new species.
K. spinicaudus’s home in southern Angola remains poorly explored, even as it has been considered as an important source of diversification and endemism in West Africa.
“Insects in general are so diverse and so important, yet we don’t have scientific descriptions or names for so many of them,” says Dr Kit Prendergast, from the Curtin School of Molecular and Life Sciences.
The new bee species she discovered, Leioproctus zephyris excellent proof that we still have a lot to learn about bee biodiversity.
The story behind L. zephyr’s name is quite interesting – it was named after Zephyr the Maremma dog, Dr Prendergast’s fellow companion. The researcher says Zephyr played an important role in providing emotional support during her PhD. The name also references the dog-like “snout” in the bee’s anatomy that she found rather unusual.

The bee species was in fact first collected in 1979, but it had to wait until 2022 to be officially described.
However, Dr Prendergast says its future remains uncertain, as it is highly specialised, and has a very restricted, fragmented distribution.
“The Leioproctus zephyr has a highly restricted distribution, only occurring in seven locations across the southwest WA to date, and have not been collected from their original location. They were entirely absent from residential gardens and only present at five urban bushland remnants that I surveyed, where they foraged on two plant species of Jacksonia.”
Honorable mention: Two scorpion species described by high-school citizen scientists
In 2019, California teenagers Harper Forbes and Prakrit Jain were looking at entries on the naturalist social network iNaturalist, when they noticed a mysterious scorpion that a citizen scientist had encountered near a lake in theMojave Desert. The species had remained unidentified since it was uploaded six years earlier.
The entry that they were looking at was a yet undescribed scorpion species whose name they would add to the fauna of California. Shortly after, they found another entry on iNaturalist that also appeared to be an unknown scorpion species.
The new species, Paruroctonus soda and Paruroctonus conclusus, are playa scorpions, meaning they can only be found around dry lake beds, or playas, from the deserts of Central and Southern California.
This is SUCH impressive work on 2 new-to-science #Scorpion species from California, published by high school students Prakrit Jain & Harper Forbes in collaboration with @ArachnologyNerd! #Arachnology 🦂
“These kids can find anything,” Dr Esposito told The Guardian. “You set them out in a landscape and they’re like: ‘Here’s every species of snake, here’s every scorpion, every butterfly,’ and it’s kind of incredible.”
Forbes and Jain were still in high school when they made their groundbreaking discoveries. Now they are in college: Forbes at the University of Arizona studying evolutionary biology and Jain at the University of California, Berkeley, for integrative biology.
