This might be a record for me: 16 mason bee cocoons in a single nesting tube. The ones on the left are larger and likely all females. The smaller ones on the right are males, who emerge first and then wait for females to come out. It's really cool how hymenopterans can control the sex of eggs they lay (males are from unfertilized eggs). Osmia georgica. #InsectHotel #BeeHotel #bees #cocoons #insects #pollinators #hymenoptera #osmia #haplodiploidy

🐛💙 Biologist Auke-Florian Hiemstra made a surprising finding while examining museum specimens: caddisfly larvae from the early #1970s were already incorporating microplastics into their protective casings.

These #underwater #insects normally build tubes from pebbles, sand, and plant matter. Finding plastic in 50-year-old specimens from non-urban streams shows how long these pollutants have affected even relatively pristine ecosystems.

If any of you nature photographers ever capture images of insects with badly damaged wings, email them to Andrew Mountcastle at Bates College. He studies how insects crash into things and has made a public request (on Bluesky) for pics. He wants them for presentations and promises to add credits.

Reading a paper about cloth moth evolution. Really interesting!

At the end of the intro, they hypothesize co-evolution between humans and synanthropic moths. Well, that sounds very unlikely but ok I guess?

Like, recent adaptations maybe, but co-evolution seems a bit extreme.

Also I would expect it to be only in the moth, it sounds unlikely that there would be any impact on human evolution besides cultural practices...

Mein Garten ist voll mit Holzbienen, die gerade fleißig damit beschäftigt sind, die nächsten Generationen zu erschaffen. Die Männchen dieser Art haben orangefarbige Fühlerspitzen und sind damit gut von anderen Arten utnerscheidbar.

EN: My garden is full of carpenter bees that are busy creating the next generations. The males of this species have orange-colored antennae tips and are thus easily distinguishable from other species.
