Winter Work Parties 2026-27

We have a busy programme of working parties all over the county starting in October into March. This has been a wonderful summer for butterflies and with your help we can make 2027 even better.

Information about all the sessions can be found here.

Sightings

Anyone can post photos of butterflies they have seen in Sussex. Recent sightings include:

28 Oct: I know it's not a butterfly but .... weeding a border yesterday, we unearthed this H Convolvuli larva about 4cm deep obviously thinking about pupating. Sadly it was slightly damaged before it was noticed. I can only think a bird must have dropped the larva a short while ago, there is no suitable foodplant anywhere near where it was found. I last saw a convolvuli here about 3 years ago.

28 Oct: Two Red Admirals and a Holly Blue on a morning stroll round Shoreham

28 Oct: The fine weather today produced a female Small Copper, two Red Admirals and a non stop Clouded Yrllow at Herstmonceux Castle gardens. I must thank the Lady Gardener for not only drawing my attention to a Red Admieal in a flower border. but also allowing me to step among the plants to photograph it !

28 Oct: A walk around the eastern sections of North Lancing was warm, sunny and breezy. I was surprised to find eight butterfly species, including a late third brood Small Heath. 10 Clouded Yellow (including a helice), 3 Holly Blue (females), 3 Red Admiral, 2 Peacock, 2 Small White, Small Copper, Speckled Wood, 2 Silver Y, Humming-bird Hawk-moth.

27 Oct: A walk from north-east Sompting to St Mary's churchyard was warm and sunny, but breezy. 15 Clouded Yellow, 6 Red Admiral, 3 Small White, Holly Blue, Small Copper, Humming-bird Hawk-moth. We seem to have gone so quickly from counting heatwaves to counting storms! It was lovely to read Neil Hulme's interesting and positive reports.

27 Oct: The Clouded Yellow season continues.....two seen today on Shoreham Beach including a nice helice...

27 Oct: Well martin i went back today to the valerian patch by the yacht club and to my surprise i found 4 Clouded Yellow! I would surmise that none of them are the same ones that i saw prior to the storms but it cheered me up anyway. Thanks for the suggestion of yours recently.

26 Oct: Hopefully, some of you may have already read or heard of the Halnaker Hill Farm BNG project, given the wide media coverage - e.g. https://www.theguardian.com/environment/2026/oct/22/thousands-of-butterflies-surprise-experts-on-restored-west-sussex-farmland Although this project is not open to the public, it does demonstrate just how rapidly nature recovery can be achieved, via a number of different routes. When I look at the wide range of habitat restoration projects breaking out all over our county at the moment, including large-scale and ambitious ones (Mill Hill and Friston Gallops immediately spring to mind, but there are many more), I'm filled with optimism and hope for the future.
