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 🤯🧪🐜

‘Almost unimaginable’: these ants are different species but share a mother
Ant queens of one species clone ants of another to create hybrid workers that do their bidding.

Wildflower plantings near crop fields are a common tool for attracting pollinators, but a new study shows pesticide applications to crops are likely to drift as far as 100 feet into these wildflower zones, potentially harming the very pollinators they're meant to attract.

Great to read this synthesis on how effective promotion measurements for urban pollinators really are! They work! Sadly, there is no data on perennial plantings yet - watch this space.

I'd like to see our opinion paper to be a starting point for a wider discussion before monitoring methodology is written in stone.
jki-research.bsky.social Julius Kühn Institute (JKI) @jki-research.bsky.social · Jul 9
The revised EU Pollinator Monitoring Scheme #EUPoMS suggests standardised methods, but lacks strong evidence for key choices. The authors from JKI urge clarification on excluding pan traps to maintain scientific integrity and public trust in the scheme.

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/JKI Researchers 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/JKI Hedges 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.

Butterflies use electrostatic force to pollinate
Two biologists showed that butterflies and moths generate enough electrostatic charge to attract pollen grains from nearby flowers, but they might attract predators in the process.
