Want to conserve #birds, #mammals and other vertebrates? Then don’t forget their #insects. Our new Nature Reviews Biodiversity paper explores the many ways vertebrates depend on insects — for food, shelter, protection and much more. I’ve written about it here: jeffollerton.co.uk/2026/09/30/w...

Want to conserve birds and mammals? Then conserve their insects – our new paper in Nature Reviews Biodiversity sets out the details

It’s sometimes easy to forget quite how much of the living world depends upon insects. That might seem an odd thing for someone who has spent much of his career studying insects and their relations…

Vac sampled by Keith Fowler. @dipteristsforum.bsky.social #ukwildlife #spiders

Distinctive looking critter with thick black front legs and elongated shape but good to have it confirmed by Nigel Cane-Honeysett, Salop spider recorder, as I know Jack Nabby about spiders

More from above but with reflections from its tube before release. There were at least a couple in the tray
