🇬🇧Potter wasp, Ancistrocerus sp. These wasps of the genus Ancistrocerus belong to the solitary potter wasps. Unlike their more social relatives, such as the common wasp or hornet, they live alone and do not build large nests. They hunt alone and take care of their offspring by themselves. Ancistrocerus wasps paralyze small caterpillars, beetle larvae, or spiders to store them as food for their larvae. 🇩🇪Lehmwespe, Ancistrocerus sp. Diese Wespen der Gattung Ancistrocerus gehören zu den solitären Faltenwespen. Im Gegensatz zu ihren sozialeren Verwandten, wie der Gemeinen Wespe oder Hornisse, leben sie allein und errichten keine großen Nester. Sie jagt allein und kümmern sich selbst um den Nachwuchs. Ancistrocerus-Wespen betäuben kleine Raupen, Käferlarven oder Spinnen, um sie als Futter für ihre Larven zu lagern. #Ancistrocerus #wasp #wespe #hymenoptera #portrait #insects #entomology #wasps #potterwasp

Researchers highlight the impact of insect decline on the abundance and diversity of microhymenoptera, which are important for maintaining #ecosystem health but often overlooked in monitoring efforts. 🔗 doi.org/10.3897/jhr.97.12823… #Hymenoptera #biodiversity

#PhDposition in #biochemistry Apply for a PhD position in the Robert Hanus Group (Chemistry of Social Insects) @IOCBPrague @CzechAcademy, funded by the #MSCADoctoralNetwork 'ModBioTerp': uochb.cz/en/open-positions/3… The project "Evolution of Terpenoid Biosynthesis in Insects" is focused on the functional characterization of a set of insect terpene synthases from unrelated insect clades and defining their common and idiosyncratic structural features acquired during their multiple independent origins. Please note: Students coming from Czech universities are not eligible for this position.

The life strategies of #parasitoids are stunningly diverse, but no wasps that attack and develop inside adult flies have ever been described. Our article describes the first one. Its hosts: Drosophila melanogaster and other species of #Drosophila #Entomology #Braconidae

Nejhorší není, že ničíme poslední kouty české přírody. Nejhorší je, že ničíme poslední kouty a ještě za to platíme horentní částky, protože si někdo na @SPUvCR opravdu upřímně myslel, že tím pomůžeme přírodě.
🧵1/2 Jsme bohatá a úplně blbá společnost. 28 milionů jsme zaplatili za zničení přirozené nivy/prameniště. Na vlhkých loukách hnízdily čejky, bekasiny, kvetly vzácné rostliny. Místo toho máme rybník s kamennou hrází, přivaděč z potoka, přítok i odtok zahloubený.
