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.
Anyone can post photos of butterflies they have seen in Sussex. Recent sightings include:
30 Oct: Another visit to the Sompting QoS field and surrounding area was warm and gloriously sunny. 32 Clouded Yellow, 7 Red Admiral, 6 Small White, 2 Brimstone (m&f), Holly Blue (m), Small Copper, Painted Lady, Peacock, Humming-bird Hawk-moth, Silver Y. Wow! Just wonderful!
30 Oct: Todays visit ro Herstmonceux turned into a bit of a puzzle when I got home. I rhought I had seen one Small Tortoiseshell twice, but cruel enlargement on the computer suggests two individuals were seen. Quite remarkable given the date. This makes three Small Torts for me this year. Also seen today, Three Clouded Yellows, and a very quick Red Admieal.
30 Oct: I have been told that Queen of Spain Fritillary have been emerging this week. Not a Sussex report but there is no reason why there shouldn't be some to find!
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.
