After months of planning, our bumblebee colonies are out at Thursley National Nature Reserve and surrounds to test the impact of Heathlands as nature's pharmacies for bumblebees. HUGE thanks to @naturalengland.bsky.social, @nationaltrust.org.uk and all the public volunteers for hosting our colonies!

Very important new paper out! The coffee berry borer beetle is the worst pest of ☕️ worldwide, and in Mexico is attacked by the wasp Cephalonomia hyalinipennis. That wasp is supposed to be in Hawaii, so why doesn’t it attack CBB here? Turns out neither are actually C. hyalinipennis!

One of the things I love about coming to Burgundy is seeing the high density of martins and swallows, and their nests. Reminds me of my childhood in England when we still had lots of insects

This sounds amazing - can’t wait to read it. I remember writing essays about pigeon-homing as an undergraduate, when it was all (excuse the pun) up in the air. Exciting that we’re still learning more about it nearly 40 years later 🐦 🧲

New evolutionary tree for all of the world's bumblebee species, from (1) slow-evolving nuclear genes, (2) fast-evolving mitochondrial genes, and (3) results from genomic data, to provide a complete starting point for comparative studies of all bumblebees www.researchgate.net/publication/...
Evolutionary tree for all 289 extant accepted published bumblebee species from 93 million MCMC generations (post convergence) by BEAST 2 for two mitochondrial genes, four nuclear genes, and ge-nomic-supported group priors, with outgroups removed. Bayesian posterior support values for each node are shown with node and descendant branch colours indicating values from blue for high values to red for low values. Selected groups are indicated with larger spots: pale blue LT/LG for long-tongued Lowland Grassland species; pale green ST/MG for short-tongued Montane Grassland species; black spots for parasitic or ‘cuckoo’ species that lack workers, including the subgenus Psithyrus and B. inexspectatus, B. hyperboreus, B. natvigi. Subgenera are named in the outer grey ring. Taxon names not appearing in this figure are interpreted as synonyms (see text).

It’s World Bee 🐝 Day! A day to celebrate these amazing insects, and to reflect on how we can support wild populations of 🐝 🐝 for the future. Museum collections are key in showing where bees used to be, setting baselines to understand impacts of stressors and set restoration/conservation targets

It’s Earth Day. This year’s focus is community action, so let’s look at specimens where the whole is greater than the sum of its parts. The amazing architecture of corals and wasp nests emerges from combined actions of many individuals. Let’s be inspired by nature to make the world a better place!

I was lucky enough to spend some time with our Entomology collection this week, and sometimes it’s the small things that stick. This is a case of ladybirds 🐞 collected by Alfred Russell Wallace (www.nhm.ac.uk/discover/who...) who co-discovered the idea of natural selection and evolution. Just wow 🤩

I’ve been thinking about scale this week. And that’s something zoology museums are great at helping us grasp. Many of our public specimens are arranged to help people understand the physical range of closely related animals, so I thought I’d share some of my favourites @zoologymuseum.bsky.social
