We discuss various strategies for locating nests of the rare and endangered above-ground nesting bumblebee species Bombus muscorum. Although we did not find any nests, we were able to track bees marked with paper strips for up to 800 m. @jki-research.bsky.social @nabu.de doi.org/10.1111/icad...

Cool approach to use expert-elicited tree attractiveness scores. Would be could to match them with field-derived data in the future.

Common FIT designs contain an upper and a lower container. They may be adjusted for #bee research by removal of the upper container: we caught very few insects and not a single bee in it, which is surprising given the results for other arthropod groups, mostly in forest research. 🐝 #monitoring #JKI

Bee communities caught with FITs mirrored communities expexted from the literature and from known preferences of specialized bees. They proved as a valid, standardizable and reliable tool for monitoring bees.

In an inital pilot study, we then focussed on flight interception traps (often called window traps) as a promising, standardizable method for monitoring bees in trees. We tested FITs in different tree species at their peak bloom, particularly focussing on the methodological aspects of this method.

Happy to share our latest publication with you. 🧵 Trees are often overlooked as relevant bee forage ressources. Realising that there is relatively little known about bees in flowering tree canopies, we searched for data and methodologies to tackle this gap. @jki-research.bsky.social

woah this is genuinely, utterly WILD Ant queens of one species produce males of another species, so she can then mate with them and produce hybrid workers! This is so gloriously weird I can't quite compute it 🤯🧪🐜 www.nature.com/articles/d41...

Pike & Rittschof pointing out that "only ∼13% of resource competition studies evaluated fitness effects of A. mellifera on wild bees" and call it a research gap. Not surprising! It's a real challenge to look at fitness, particularly for rare species, which might be the most vulnerable.

Researchers at our Institute for #Bee Protection are currently collecting data on the occurrence of honeybees and wild bees in agricultural landscapes. Systematic data collection over several years will provide a robust reference for future interval monitoring. #WorldBeeDay www.julius-kuehn.de/en/bs
Some of the survey sites are located in intensively managed agricultural areas. Just in these locations, the field margins show an unexpectedly diverse flora during the course of the year (note the difference between end of March and beginning of May 2025). At this site, located in the Salzland district of Saxony-Anhalt, the halictid bee (Lasioglossum xanthopus) visits flowers of field bugloss (Lycopsis arvensis), among others.
Photo: Dr Severin Polreich/JKIResearchers at the JKI Institute for Bee Protection collect pan-trap samples. The spectrum of bee species and other flower-visiting insects is determined using DNA metabarcoding later on. 
Photo: Dr Severin Polreich/JKIHedges are important landscape elements, providing not only food but also nesting opportunities and sun-exposed surface for warming up and resting (here on field maple, Acer campestre), which may also have a positive effect on the pollination activity of bees in the cooler spring.
