Saving Butterflies and Moths in Wales

Brown Hairstreak (female/upperwing)

The Brown Hairstreak butterfly has suffered significant declines across the UK, losing almost half of its population in the last 30 years. In stark contrast to the national picture, our work has meant Brown Hairstreak numbers have remained relatively stable in Wales. 

Conservation measures have been introduced in Carmarthenshire, Pembrokeshire and Ceredigion and have allowed this butterfly to maintain its place in the sanctuary of the South-west Wales landscape.

Funding for this vital work has now run out. Without further support the future of the Brown Hairstreak in Wales is under threat.

Secure the future of Gwent’s butterflies and moths.

A number of our rarest moths, including the Scarce Hook-tip, Drab Looper and Silurian can be found in Gwent. The area is also home to some of the best butterfly habitat in Wales, including Blackrock Quarry and Caerwent, which are strongholds for a wide variety of species including the Small Pearl-bordered Fritillary and Green Hairstreak. 

We need to conserve areas of habitat that support rare species, conduct more research and increase the level of surveying work in this area, to ensure Gwent continues to provide a haven for wildlife.

Support vital conservation work

The threatened Marsh Fritillary and other target species rely on ongoing habitat management work in order to survive in Wales. Clearance work is often necessary to stop sites becoming overgrown and unsuitable for the plants that butterflies rely on for food and shelter. We need to raise funds for health and safety training and equipment to undertake this essential work at a range of sites between Carmarthenshire and Monmouthshire. 

Our South Wales Branch has secured £2,000 from Pen y Cymoedd Wind Farm Micro Fund to purchase the necessary power tools. We need your help to raise the necessary match funding for this work to take place.
