@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)!

@cnhs1857.bsky.social Field Study. On Sunday, August 10 we will look at Coe Fen and Sheep’s Green. Meet at the bridge over the weir by Scudamore’s at the end of Mill Lane TL447580 at 2pm. All welcome.
