The SxBC photo competition is back!
We're inviting photographers to submit their best Sussex butterfly photographs to our annual competition. Whether it's a rare species in flight or a perfect close-up of delicate wing patterns, we want to see it.
The results will be announced at the Members Day held on Sunday the 22nd November. For more information click here.

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:
17 Oct: Despite the cold NE wind this afternoon at Thorney Island we still managed to see four species of butterfly. Clouded Yellow 24, Red Admiral 8, Speckled Wood 2 and a Small White.
17 Oct: A gentle stroll over the Amberley Downs, savouring what Sussex has to offer, even this late in the season. No rarities but happy enough with what I saw: 25 Clouded Yellows, 4 Small Whites, 1 male Common Blue, 1 Small Copper and 1 mystery moth! The steep slopes of the Amberley Downs makes photography a little tricky, but sometimes works in our favour as we can achieve different types of photos. Unusually, for me, I was able to identify this moth (as I had other images to check), but the members might like to have a guess (without the help of AI). As a dynamic photo, nectaring on Devilsbit Scabious, and seen side-ways on, I rather like it. As I have never photographed a mating pair of Clouded Yellows, I rather liked that, too.
17 Oct: A walk north of the A27 from east Sompting to Lyons Farm was in glorious sunshine and felt too warm to wear a jacket. Most of the butterflies were in the Queen of Spain field, but there was even a Humming-bird Hawk-moth inside Sainsbury! 24 Red Admiral, 21 Clouded Yellow, 9 Holly Blue, 5 Small White, 4 Humming-bird Hawk-moth, 3 Common Blue, 2 Small Copper, 2 Speckled Wood, Silver Y. A fresh-looking Volucella zonaria was a surprise to me this late in the season.
17 Oct: The butterfly season continues. A walk round Shoreham and onto the beach turned up a Red Admiral, Small White and 5 Clouded Yellows. The latter were all on the beach and included a' flock' of four! Not sure of the collective noun for a group of Clouded Yellows. Is there such a thing?
17 Oct: The season continues into the third week of October along Eastbourne seafront, so a couple of hours were well spent in the company of the many (20+) Clouded Yellows including two helice form females. Several pairs of yellows were witnessed attempting cop', which is also encouraging. Also seen were a fresh looking Red Admiral, a Common Blue female, a single Small Copper and numerous Small Whites, plus three Painted Ladies.
16 Oct: A walk up the River Adur's west bank to the footbridge and back down the east bank to Shoreham produced one Small White near our starting point and a Red Admiral + a Clouded Yellow near the bridge on the east. I disturbed the Red Admiral trying to get close it and luckily also disturbed the Clouded Yellow hidden nearby.
15 Oct: Hummingbird Hawk moth in my garden. Unfortunately I don't have flowers suitable so I need to resolve that!
15 Oct: A few sightings in the garden over the last few days. 8th Clouded Yellow and Small Copper, 11th Clouded Yellow and Small Copper, 13th Clouded Yellow, 14th Clouded Yellow and today 15th Speckled Wood. We have also had hummingbird hawk moths every single day.

New colonies of Wood White were recently discovered in West Sussex and our branch is planning to learn more about this rare butterfly.
We are organising a coordinated survey and are looking for volunteers. For more information on the Wood White Project in Sussex click here.

Throughout the year we receive interesting sightings records. We have started an exercise to identify notable sightings and look for patterns during a month with a little help from an AI assistant.
