We will be closing this account shortly. We are on Bluesky so it will be lovely to see you there!

Lunch in the garden today with this Brimstone feeding on the flowers of Daphne odora aureomarginata.
Perhaps the word 'butterfly' originates from the yellow colour of male Brimstones like this one.

My first butterfly of 2026 on a spring-like Saturday. This Red Admiral emerged from hibernation to bask in the sunshine close to a Daphne odora, the most fragrant 'butterfly bush' of winter/spring. #wildlifegarden

I've missed #MothMonday but look who I just found, nestled in an early anemone flower!
An emerald green caterpillar, that's who! Of a moth I believe #savebutterflies @UpperThamesBC @BCWarwickshire

The clock is ticking for the rare Dark Bordered Beauty ⏰
There are just 24 hours left to have your donation matched in the Big Give. Together we can bring this specialist moth back from the brink 👉 donate.biggive.org/campaign/…

It is always lovely this time of year to go for an evening woodland walk by torchlight and look for the moths of winter @savebutterflies
A very enjoyable UTB Members Day and a big thank you to the 4 excellent speakers. Thanks also to all the UTB volunteers working behind the scenes to make the day run smoothly!

Abingdon, Oxfordshire. 25.9.2025 Clouded Yellows, Colias croceus, on the wing in the clover field, which is now looking really lush after recent rain.

Not seen Small Coppers much in my home visits to the Tattenhoe area in recent years, so 5 together today made a great sight, especially being solitary in most of my past sightings here. Also a pristine Brown Argus alongside a few Common Blues yesterday and today. @UpperThamesBC

A selection of Clouded Yellow photos from the last few weeks. 4 sites (Berks and Oxfordshire), 7 visits, much running around field edges and hillsides.

Clouded Yellows from Yoesden Bank this morning before it got just too scorchio for chasing up and down hillsides like a geriatric lunatic. I went early on purpose to see the Adonis Blues before they got too active in the sunshine, these were a nice bonus
