Welcome to the Yorkshire Branch of Butterfly Conservation  

Butterflies are not only beautiful and fascinating creatures but are also highly responsive to the environment. David Attenborough described them as  'A thermometer of the health of our natural world'  Many species of butterfly are in decline and a quarter are facing extinction.  We have lost more than 98% of our traditional meadows and woodland in recent times so it is crucial  we raise awareness about the threats facing our butterflies, moths, their habitats and our natural environment.  Yorkshire Branch  work in partnership with land owners, local authorities, conservation bodies, businesses and the local community to achieve this. Here in Yorkshire  the Duke of Burgundy and Pearl Bordered  Fritillary are particularly vulnerable due to habitat loss and increasingly susceptible to extinction. Yorkshire also has the only remaining colony of the  Dark Bordered Beauty Moth in England, on Strensall Common and is on the brink of extinction.  

Become a member today and help us save butterflies, moths and their habitats. There are many rewarding roles volunteering in recording and conservation just take a look at our Branch leaflet HERE . We have a real challenge when 60% of children in the UK have never seen a Peacock butterfly according to a YouGov Survey and  78% of parents are concerned that children don’t spend enough time interacting with nature.  Founded in 1981 Yorkshire branch has more than 1800 members and over 100 transect walkers go out each week in summer  to monitor  butterfly sites across the county while dozens more join work parties to maintain habitat for our rarest species.

24th March:  A joint meeting with Yorkshire wildlife looking at the latest news affecting butterflies and Yorkshire wildlife presents an overview of it seminal publication on the State of Yorkshire's Nature. Nick Hall presents the reasons to monitor butterflies and issues of recording in 2024 poor weather. Nick presents the 20024 annual review in a historical context of the last 150 years and the last 20 years and how climate factors have impacted our species picking out how 2024 fared against other very poor years like 2016 and 2009 and comparing it to the national picture.  We introduce all our new transects and their walkers and discuss issues of identification of the tricky White and Skipper families 

6th March Its Brimstone lift-off day with temperature touching 17'C in Yorkshire. For the majority of us a Brimstone will be our first butterfly of the year. I was lucky enough to spot two at the Yorkshire Butterfly reserve at Shipley Station while advising on improving the meadow. Comma comes in at second place for first butterfly seen followed by Red Admiral, then Peacock. Just a handful of Small Tortoiseshells have been seen all away from the Vale of York. Birmstones seen currently are nearly all male as they feed and become sexually mature awaiting females to emerge in about another week. If you have an Alder buckthorn in the garden you likely will see the eggs starting to appear later this month. Quite often you see the eggs before the butterfly being quite conspicious ice blue colour on the buckthorn shoot tips. Most will be eaten by hungry Blue Tits before they hatch. Females lay on small usually isolated buckthorns in an effort to thwart the systematic searching of blue tits!

21st Feb. A fabulous talk from Mike Slater on ways of bringing back the Small Blue. Should we not  copy this in Yorkshire on the  magnesian limestone ridge from Lindrick to Catterick?
