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.

Great exhibition that many CNHS members attended last night. Our patron, Dafila Scott was there too with some of her wonderful paintings. #dafila.bsky.social #staplefordgranary.bsky.social

A warm Saturday for our fieldwork day meant we found lots of non-bryophytes in Paradise NR & nearby. #ukdragonflies #ukbutterflies

Field Studies 8th November - Paradise NR (and round about). We recorded about 40 bryophytes (5 liverworts and approx. 35 mosses).

Autumn fungi found on our recording session in Paradise NR/Coe Fen & Sheep's Green. The most numerous were the Fairy inkcaps, and the most interesting was the Cowpat gem fungi (Cheilymenia granulata) I also enjoyed the Chocolate slime mould (Stemonitis sp.) in the gloom of the wood in Paradise.

@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.

All welcome; in person at the DAB, or online via zoom (register in advance). What could be more relevant for natural historians than a talk called 'The Past and Future of Natural History'.

Lots of people turned out for the CNHS Plant gall survey yesterday. Some curious bullocks tried to join in which made examinations by loupe difficult. The Oak trees provided the best number of galls, including Andricus gemmus, perhaps new to central Cambridge.

A Wasp spider (Argiope bruennichi) in a central Cambridge meadow . The main food item for this spider is orthoptera (crickets and grasshoppers), so perhaps it has caught one of the many Field grasshoppers in the meadow.

New species for Britain found in Cambridge - Otiorhynchus corruptor. It has been found in grapes in a supermarket in Wales before, but we are not aware of any other records of it from outdoors in Britain. It is similar to O. sulcatus but corruptor has broad areas of scales with a bare patch.

Field Study trip to Wandlebury with Jonathan Shanklin, Sunday Aug 31st. Meet by the cycle stand and information board at 2pm. All welcome. 550 taxa reported from site but 150 haven't been seen for a decade so we shall be looking for plants.
