We collected two Polypody fronds for Cambridge University Herbarium last year. Have you ever wondered how you catalogue and store specimens? Juliet has kindly sent in some photos showing them catalogued and put into the Herbarium. #CambridgeUniveristyHerbarium

@cnhs1857.bsky.social CNHS had a stall at the Big Biology Day last weekend. People enjoyed exploring and chatting about Bees, moths, seeds, fungi, an antler, fossils etc. the fossilized shark teeth were the biggest draw - especially with the younger crowd.

Pleased to find a new species for Britain, confirmed today. The weevil Otiorhynchus corruptor - found outside in Cambridge on 22nd August 2025. (Of course, I recorded it as a Vine weevil, so thanks to Mark Gurney and Max Barclay for correcting my mistaken identification)!

CNHS led a biodiversity walk around the new Marleigh development on Tuesday evening. Despite the pouring rain it was good to see quite a few residents turning up for the walk and we managed to find and record quite a lot of wildlife (mainly plants though!). @cnhs1857.bsky.social
