It was an honour to bring some #WaspLove to the #Oxford @naturerecovery.bsky.social last week, in the framework of the natural capital of wasps and their contributions to people. What a fabulous audience 🥰.

If you've ever asked the question: 'What's the point of wasps?' you should watch our most recent #Nature Seminar, 'The Natural Capital of Wasps'. @waspwoman.bsky.social Seirian Sumner will convert you! youtu.be/ELI_8KkwJm0

We had a new paper out yesterday in @royalsocietypublishing.org Biology Letters. About how the cranial feathers of male Golden and Lady Amherst’s Pheasants affect their visual fields. Nice to see it picked up The New York Times and Science. Paper link below.
