Information about all the sessions can be found here.
Anyone can post photos of butterflies they have seen in Sussex. Recent sightings include:
14 Nov: My walk today through the Downs to Stoke Bottom was absolutely beautiful, made even better with a Red Admiral and nine Clouded Yellow, including a Helice in Stoke Bottom. I arrived around 1.30pm, they were looking to roost by 3 as shadows were extending along the valley.
14 Nov: Red Admiral feeding on a rotting pear left on our pear tree in the front south facing garden.
14 Nov: I think I saw a hummingbird hawk moth in haywardsheath a&e Could be wrong and sorry for very poor quality image!
13 Nov: And so it continues! A bright, frosty day and a surprising Clouded Yellow encounter on the SDW!
13 Nov: Taken along the sea front of felpham bognor Regis on my morning walk. Friday 13th 2026
13 Nov: The temperature never rose above 7°C after a slight frost, but bright sun brought out an amazing five species of butterfly. 2 Clouded Yellow, Painted Lady, Small Copper, Speckled Wood, Red Admiral. All but one in Lancing Manor Grounds.
13 Nov: Two Clouded Yellow and 2 Red Admiral on the southern end of the Island.
12 Nov: I'd just said to Val that we'd probably set off a bit too late in the afternoon to see any butterflies at the sea front- around 2:30pm - when something fluttered into the road and off behind us. Judging from dull colouring, size and somewhat jerky flight it was a Silver-y Moth. Even less expected, Val spotted a second similar moth in Marine Gardens. But no butterflies.
