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' Almost every species of butterfly is in decline and a quarter are facing extinction. We have lost more than 97% 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 wil be 40 years old this year and has more than 1800 members.

Upcoming Event : A thought provoking talk and presentation from Andy Suggitt
Online event at 19:30 on Monday 31 January 2022. Register for free HERE
Accelerating climate change is increasing the risk of extinction for cold- or wet-dwelling butterfly species, and it is thought that up to a sixth of all biota faces worldwide extinction by the end of the century. However, evidence from the last glacial maximum suggests that affected species might survive in refugia, areas with an atypical climate (or microclimate) that buffer species from the worst of these changes. In this talk, Andy will describe some early results from a national survey of four northern butterfly species thought to be possible beneficiaries of this so-called refugial effect.
Your Guide to the Website
The Red list of Butterfly species species has been updated High Brown Fritillary and Large Blue, which move to Endangered and Near Threatened respectively. Duke of Burgundy and Pearl-bordered Fritillary have also been assessed at lower risk this time, while remaining on the Red List, both moving from the Endangered category to Vulnerable. Other species have moved in the opposite direction. Large Heath and Grayling have moved from Vulnerable to Endangered, reflecting increased extinction risk for these butterflies. In addition, several species that were not deemed at risk in the 2010 assessment are now included in the Red List, such as Swallowtail, Silver-spotted Skipper, Small Heath, Adonis Blue and Chalk Hill Blue, which have all moved from Near Threatened to Vulnerable, and Wall, which has moved from Near Threatened to Endangered.

17 January - The Purple Emperor: An Idiosyncratic species with Dennis Dell
If you missed the fantastic live talk by Dennis you can watch the recording below. Dennis describes how this species has expanded its range northwards to now knocking on Yorkshire's door, in fact its likely it is already here. Dennis explains how to understand its idiosyncrasies to give you the best chance of discovering this species.

Calling all butterfly recorders: The DECIDE Project needs your help
This interesting citizen science project is developing a tool for recorders to use to find out where biological records are needed most to improve species distribution models. In turn this will enable data users such as land managers, planners and policy makers to make better decisions. The tool has been co-created with the recording community. The DECIDE team would really appreciate it if you give your feedback. Try it out : https://decide.ceh.ac.uk/info/decide_info as they develop it further.
