Our new paper, led by Dr. Yurii Geryak, reports the first occurrence of the invasive pest moth Spodoptera frugiperda in Ukraine and Eastern Europe, with the earliest confirmed record dating back to June 2021.

Thank you! ❤️❤️❤️🥰

Unforgettable #Hymathon2025, a virtual symposium of International Society of Hymenopterists Hymathon is the society’s annual 24-hour-long marathon of Hymenoptera! Join online from anywhere in the world to listen to presentations from Hymenopterists, present your own research, participate in social events and make new connections. It is full of research talks, fun events, and more than a small amount of chaos as the 24 hours reaches the end! Hymathon 2025 occurred on 4–5 December 2025, with four sessions over the 24 hour period.

Unforgettable #Hymathon2025 ❤️

Looking forward to our new meetings with @hymenopterists.bsky.social

Poster presented on the 2nd International Electronic Conference on Entomology. Title “Potential Invasion and Distribution of Lymantria mathura in Ukraine: Risk Assessment and Management Strategies”, authors KLECHKOVSKIY, TITOVA, BONDAREVA and KALIUZHNA (Ukraine). Lymantria mathura (Moore, 1865), the rosy gypsy moth, is a polyphagous defoliator from the family Erebidae, which inhabits deciduous forests mainly in South and Southeast Asia. The broad trophic spectrum of this species makes it an important pest that threatens forests, urban greenery, ornamental plants, and fruit trees. Due to climate change, this species could become a threat beyond its natural range and the aim of our research was to assess the risk of invasion and establishment of L. mathura in Ukraine and to model the potential distribution of natural enemies of this moth. GIS modeling in MapInfo Pro 15.0 and IDRISI Selva was used to model the potential distribution of L. mathura, and MaxEnt was used to model the potential distribution of entomophagous insects known to be effective in L. mathura biocontrol. We found that the potential range of L. mathura covers almost all of Ukraine, except for the Carpathian highlands. The most important bioclimatic factors influencing its establishment are the mean annual temperature, the temperature of the warmest month, and the sum of active temperatures above 10 ℃, while the limiting factor is the mean temperature of the coldest month. Modeling suggests that natural enemies such as Cotesia melanoscela (Hymenoptera: Braconidae), Compsilura concinnata, and Carcelia gnava (Diptera: Tachinidae) could play a crucial role in biological control if L. mathura invades Ukraine. Due to its high risk of introduction, broad climatic tolerance, excellent flight ability, and numerous suitable host plants, L. mathura poses a serious threat to Ukraine's plant resources. A key risk management strategy could be its inclusion in List A1 (absent) of the Ukrainian Regulated Pests List.

I am happy to be a part of the 2nd International Electronic Conference on Entomology organized by Insects, MDPI.

Oh, I got confused by these broad antennae)) Very nice snowflakes, by the way😍

I'm really curious) Paussinae beetles?

Book eaten by bookworms

What can happen to a book if nobody reads it - actual bookworms 🐛🪱

Today we've been called to check the situation with books and other artifacts damage from insects in local library. Lower number of readers could be a serious challenge to a library, especially for the old books.

Thank you, Lars! 💙💛

It's important: I am alive and working thanks to the Military Forces of Ukraine and the international support of my country. Thank you🇺🇦
