The International Congress of Entomology 2024 (ICE2024), which took place on August 25-30 2024 in Kyoto, Japan, was arguably the biggest entomology event of the year. For the Pensoft team, it was an excellent chance to catch up with our authors and editors and discuss new partnerships.
At the Kyoto International Conference Center, entomologists visited lectures, symposia, and poster presentations, but they also enjoyed insect-themed haikus, origami, and artworks, and got to sample some edible insects.
Meeting our authors in person was a chance for us to gather valuable feedback and make sure we are doing our best to provide entomologists with a frictionless process that makes their published research shine.
Scientific illustrator Denitsa Peneva’s beautiful works adorned Pensoft’s stand; Mostafa Ghafouri Moghaddam, subject editor at ZooKeys and Biodiversity Data Journal and author at a number of Pensoft-published journals even got to take one of her prints home after winning a raffle that Pensoft organised. He won a beautiful illustration of Bombus fragrans on Trifolium pratense.
Pensoft’s founder and CEO and one of the founding editors of the company’s flagship journal ZooKeys, Prof. Lyubomir Penev, was there representing the company and meeting with fellow entomologists.

They also got the chance to learn about the ARPHA Platform, a next-generation publishing solution that offers a streamlined and efficient workflow for authors, reviewers, and editors.
At ICE2024, Pensoft also presented its newest open-access jorunal, Natural History Collections and Museomics. A peer-reviewed journal for research, discussion and innovation of natural history collections, NHCM will publish under a diamond open access model, allowing free access to published content without any fees for authors or readers.
In addition to its publishing endeavors, Pensoft also presented some of the EU-funded pollinator projects that it takes part in such as Safeguard, PollinERA, and WildPosh.
ICE2024 was a chance to advance entomological science and foster collaboration within the global scientific community. For those who missed the chance to connect with Pensoft in Kyoto, the company’s journals and platforms remain accessible online, offering opportunities to read and produce groundbreaking research in insect diversity and ecology.
European researchers have discovered a new species of osmiine bee with an unusual geographic distribution.
Hoplitis onosmaevae is currently found exclusively in the Mercantour National Park in the French Alps and disparate mountainous regions in Turkey and Northern Iraq. The distance of more than 2000 km between these areas highlights a significant biogeographic disjunction.
Distribution map of Hoplitisonosmaevae.
Described in the open-access journal Alpine Entomology, the new bee species demonstrates unique ecological characteristics such as its distinct nesting behaviour in dead wood.
Presumed to only harvest pollen from Onosma species, it has a long proboscis, which is likely an adaptation to collect nectar from the long-tubed flowers of this genus.

The strongly disjunct distribution of Hoplitis onosmaevae has important implications for conservation. The species likely has a very narrow ecological niche, making it highly susceptible to future changes in its habitats, for example due to changes in agricultural practices or to climate change.

“The consideration of the few known populations of this species in France is very important in the conservation field,” says lead author Matthieu Aubert, freelance entomologist and member of the Observatoire des Abeilles association.
“This study highlights the incredible diversity of wild bees and that we still have a lot to learn from our environment, even in western Europe,” he continues.
The researchers emphasise the need for detailed conservation plans in the southwestern Alps to ensure the survival of Hoplitis onosmaevae, considering its highly specialised ecological niche and consequently its vulnerability to habitat changes. Their proposals for initial conservation steps can be found in the full research paper.

October and November 2023 were active months for the Pensoft team, who represented the publisher’s journals and projects at conferences in Europe, North America, South America, Oceania and Asia.
Let’s take a look back at all the events of the past two months.
The Biodiversity Information Standards Conference 2023
The annual gathering is a crucial platform for sharing insights, innovations, and knowledge related to biodiversity data standards and practices. Key figures from Pensoft took part in the event, presenting new ways to improve the management, accessibility, and usability of biodiversity data.
Prof. Lyubomir Penev, founder and Chief Executive Officer of Pensoft, gave two talks that highlighted the importance of data publishing. His presentation on “The Biodiversity Knowledge Hub (BKH): A Crosspoint and Knowledge Broker for FAIR and Linked Biodiversity Data” underscored the significance of FAIR (Findable, Accessible, Interoperable, and Reusable) data standards. BKH is the major output from the Horizon 2020 project BiCIKL (Biodiversity Community Integrated Knowledge Library) dedicated to linked and FAIR data in biodiversity, and coordinated by Pensoft.

–
As we approach the end of 2023, Pensoft looks back on its most prolific and meaningful year of conferences and events. Thank you to everyone who contributed to or engaged with Pensoft’s open-access journals, and here’s to another year of attending events, rewarding important research, and connecting with the scientific community.
All journals published by Pensoft – each using the publisher’s self-developed ARPHA Platform – provide extensive and transparent information about their costs and services in line with the Plan S principles.
In support of transparency and openness in scholarly publishing and academia, the scientific publisher and technology provider Pensoft joined the Journal Comparison Service (JCS) initiative by cOAlition S, an alliance of national funders and charitable bodies working to increase the volume of free-to-read research.
As a result, all journals published by Pensoft – each using the publisher’s self-developed ARPHA Platform – provide extensive and transparent information about their costs and services in line with the Plan S principles.
The JCS was launched to aid libraries and library consortia – the ones negotiating and participating in Open Access agreements with publishers – by providing them with everything they need to know in order to determine whether the prices charged by a certain journal are fair and corresponding to the quality of the service.
According to cOAlition S, an increasing number of libraries and library consortia from Europe, Africa, North America, and Australia have registered with the JCS over the past year since the launch of the portal in September 2021.
While access to the JCS is only open to librarians, individual researchers may also make use of the data provided by the participating publishers and their journals.
This is possible through an integration with the Journal Checker Tool, where researchers can simply enter the name of the journal of interest, their funder and affiliation (if applicable) to check whether the scholarly outlet complies with the Open Access policy of the author’s funder. A full list of all academic titles that provide data to the JCS is also publicly available. By being on the list means a journal and its publisher do not only support cOAlition S, but they also demonstrate that they stand for openness and transparency in scholarly publishing.
“We are delighted that Pensoft, along with a number of other publishers, have shared their price and service data through the Journal Comparison Service. Not only are such publishers demonstrating their commitment to open business models and cultures but are also helping to build understanding and trust within the research community.”
said Robert Kiley, Head of Strategy at cOAlition S.

The Zeyheria montana shrub is quite common in the Brazilian Cerrado and is known to have extrafloral nectaries on the leaf blade that attract patrolling ants such as the aggressive Ectatomma tuberculatum. The ant, in turn, defends the leaves against the action of herbivores. However, extrafloral nectaries can distract ants on the leaves, segregating them from the reproductive parts and preventing them from driving away pollinators, which can benefit the action of florivores and nectar robbers.

Surprisingly, in southeastern Brazil, we observed a second defensive mutualism occurring on the reproductive tissues of these shrubs between E. tuberculatum and the treehopper Guayaquila xiphias, which provides the ant with honeydew in exchange for protection. This trophobiosis relationship (interaction between ants and phytophagous hemipterans that secrete sugary exudates) seems to be effective not only in the defense of floral buds and flowers, but also of the fruit, which, despite being dry, contains a lot of water in its formation and is attacked by beetles of the Curculionidae family.
The treehoppers G. xiphias at the base of Z. montana fruits.
As far as we know, this is the first case reported in the literature of a double defensive mutualism occurring simultaneously on a single plant species. Given this record, important questions arise regarding these interactions. Is the trophobiosis that occurs in reproductive organs capable of increasing the fitness of these plants? Although these ants are probably also scaring away possible pollinating insects, could the fact that Z. montana is primarily pollinated by hummingbirds offset this loss given that hummingbirds are larger and perhaps immune to ant attacks?

Our record raises more questions than it answers. Long-term Z. montana population studies would help improve our ecological understanding of these interactions.
By the time authors – who have acknowledged third-party financial support in their research papers submitted to a journal using the Pensoft-developed publishing platform: ARPHA – open their inboxes to the congratulatory message that their work has just been published and made available to the wide world, a similar notification will have also reached their research funder.
This automated workflow is already in effect at all journals (co-)published by Pensoft and those published under their own imprint on the ARPHA Platform, as a result of the new partnership with the OA Switchboard: a community-driven initiative with the mission to serve as a central information exchange hub between stakeholders about open access publications, while making things simpler for everyone involved.
All the submitting author needs to do to ensure that their research funder receives a notification about the publication is to select the supporting agency or the scientific project (e.g. a project supported by Horizon Europe) in the manuscript submission form, using a handy drop-down menu. In either case, the message will be sent to the funding body as soon as the paper is published in the respective journal.
“At Pensoft, we are delighted to announce our integration with the OA Switchboard, as this workflow is yet another excellent practice in scholarly publishing that supports transparency in research. Needless to say, funding and financing are cornerstones in scientific work and scholarship, so it is equally important to ensure funding bodies are provided with full, prompt and convenient reports about their own input.”
comments Prof Lyubomir Penev, CEO and founder of Pensoft and ARPHA.
“Research funders are one of the three key stakeholder groups in OA Switchboard and are represented in our founding partners. They seek support in demonstrating the extent and impact of their research funding and delivering on their commitment to OA. It is great to see Pensoft has started their integration with OA Switchboard with a focus on this specific group, fulfilling an important need,”
adds Yvonne Campfens, Executive Director of the OA Switchboard.

Invasive insects can be vectors of diseases, cause damage to agriculture and forestry, and threaten native biodiversity. Recognising this dramatic impact, the open-access journal Alpine Entomology, published by Pensoft on behalf of the Swiss Entomological Society, opened a dedicated topical collection that is already accepting submissions.
Impacts of alien insects in the Alpine ecosysteminvites scientists working on invasive species and plant-insect interactions in Alpine regions to openly publish their research articles, review articles, and short communications on, among others, trends or changes in biogeography of emblematic species, shifts in current distributions, or niche replacement.
The new article collection will be edited by Oliver Martin of ETH Zürich, subject editor and editorial board member at Alpine Entomology, Stève Breitenmoser, and Dominique Mazzi.
“Recent years have seen a worldwide increase in invasions by alien species, especially plants and insects, mostly due to trade and climate change,” they explain, noting that although numerous studies exist on the topic, few of them focus on the Alpine areas.
“With this collection we hope to generate exciting discussions and exchange within the scientific community interested in this very particular and sensitive ecosystem,” the editors say, inviting authors to submit their manuscripts assessing the possible impacts of invasive insects on mountain areas.
The collection will remain open for submissions for the next two years. In the meantime, the accepted manuscripts will be published on a rolling basis, as soon as they are ready for publication.
Discovery of the first moth species to mine the leaves of the highly poisonous Alpine rose

An Austrian-Swiss research team was able to find a previously unknown glacial relic in the Alps, the Alpine rose leaf-miner moth. It is the first known species to have its caterpillars specializing on the rust-red alpine rose, a very poisonous, widely distributed plant that most animals, including moths and butterflies, strictly avoid. The extraordinary record was just published in the peer-reviewed scientific journal Alpine Entomology.
Poisonous host plant
The rust-red alpine rose (Rhododendron ferrugineum) is among the best-known and most attractive plants due to its flowering splendor – at least for humans. It is, in fact, a highly poisonous plant, strictly avoided by grazing animals. For insects, the alpine rose is attractive at most as a nectar plant; insect larvae, on the other hand, develop on it only in exceptional cases. This also applies to Alpine butterflies and moths, which leave Alpine roses largely untouched despite their wide distribution. Therefore, the discovery of a highly specialized species in the Alps came as a complete surprise.
Chance find

Since alpine roses are unattractive to caterpillars and no insect the entire Alpine region was previously known to specialize on them, butterfly and moth experts had considered them rather uninteresting and ignored them in their research. The discovery of the alpine rose leaf-miner wasn’t the result of a targeted search: it was a pure stroke of luck.
During a cloudy spell in July this year, researchers surveying the butterflies in Ardez in the Engadine valley, Switzerland, happened to take a break exactly at an infested alpine rose bush.
“The accidental sighting of the first caterpillar in an alpine rose leaf was an absolute adrenaline rush, it was immediately clear that this must be an extraordinary species,”
Peter Huemer, researcher and head of the natural sciences department of the Tyrolean State Museums
Peter Huemer, researcher and head of the natural sciences department of the Tyrolean State Museums, and Swiss butterfly and moth expert Jürg Schmid came back in late July and early August to look for caterpillars and pupae and find out more about this curious insect. The extended search yielded evidence of a stable population of a species that was initially a complete enigma.
Life in the leaf
Leaf-mines of the alpine rose leaf-miner moth on Rhododendron ferrugineum in Ardez, Graubünden, Switzerland. Photos by Peter Huemer
The alpine rose leaf-miner moth drills through the upper leaf skin and into the leaf interior immediately after the caterpillar hatches. The caterpillar then spends its entire life until pupation between the intact leaf skins, eating the leaf from the inside. Thanks to this behavior, the caterpillar is just as well protected from bad weather as from many predators such as birds, spiders, or some carnivore insects. The feeding trail, called a leaf mine, begins with a long corridor and ends in a large square-like mine section. The feces are deposited inside this mine. When the time comes for pupation, the caterpillar leaves the infested leaf and makes a typical web on the underside or a nearby leaf. With the help of several fine silk threads, it produces an elaborate “hammock”, in which the pupation finally takes place. In the laboratory, after about 10 days, the successful breeding to a moth succeeded, with a striking result.
Enigmatic glacial relic

Huemer and Schmid were surprised to find out that the moths belonged to a species that was widespread in northern Europe, northern Asia and North America – the swamp porst leaf-miner butterfly Lyonetia ledi. By looking at its morphological features, such as wing color and pattern, and comparing its DNA barcodes to those of northern European specimens, they were able to confirm its identity.
Habitat of the alpine rose leaf-miner moth in Engadine/Switzerland with Rhododendron ferrugineum. Photo by Jürg Schmid
The Engadine population, however, is located more than 400 km away from the nearest other known populations, which are on the border of Austria and the Czech Republic. Furthermore, the species lives in northern Europe exclusively on swamp porst and Gagel bush – two shrubs that are typical for raised bogs and absent from the Alps. However, the researchers suggest that in earlier cold phases – some 22,000 years ago – the swamp porst and the alpine rose did share a habitat in perialpine lowland habitats north of the Alps. It is very likely that after the last cold period and the melting of the glaciers, some populations of the species shifted their host preference from the swamp porst to the alpine rose. The separation of the distribution areas of the two plants caused by subsequent warm phases inevitably led to the separation of the moth populations.
Extinction risk

The Alpine Rose Leaf-miner Moth is so far only known from the Lower Engadine. It lives in a steep, north-exposed, spruce-larch-pine forest at about 1,800 m above sea level. The high snow coverage in winter and the largely shady conditions in summer mean that alpine roses don’t get to bloom there. The scientists suspect that the moth species can still be discovered in places with similar conditions in the northern Alps, such as in neighboring Tyrol and Vorarlberg. Since the moth is likely nocturnal and flies late in the year, probably hibernating in the adult stage, the search for the caterpillars and pupae is more promising. However, the special microclimate of the Swiss location does not suggest that this species, which has so far been overlooked despite 250 years of research, is widespread. On the contrary, there are legitimate concerns that it could be one of the first victims of climate change.

“Trends in Arthropods of Alpine Aquatic Ecosystems” is the first topical collection for the journal of the Swiss Entomological Society
The open-access, peer-reviewed scholarly journal Alpine Entomology, published by Pensoft on behalf of the Swiss Entomological Society, announced its very first topical collection of articles, which will be focusing on arthropods associated with aquatic ecosystems in mountainous regions.
The journal is currently inviting scientists, working on aquatic fauna from alpine habitats, to openly publish their research articles and short notices that provide evidence how arthropods’ biogeography, species communities, distribution, behaviour and morphology have changed in recent times.
“Aquatic invertebrates are key indicators of global or local changes. Furthermore, many aquatic ecosystems are closely linked to mountains because they originate in them. Many valuable unpublished datasets on aquatic arthropod fauna may therefore be available from mountainous regions,”
The aim of the “Trends in Arthropods of Alpine Aquatic Ecosystems” collection is to bring together data and findings about what many agree is the most impacted type of environment on Earth: aquatic ecosystems, especially running waters.
The collection will remain open for submissions for the next two years. In the meantime, the accepted manuscripts will be published on a rolling basis, as soon as they are ready for publication.
