Rare Moth Discovered in North Wales Wetland
1 Oct
Summary
- A rare Bog Grass Moth was found at Cors Geirch National Nature Reserve.
- Nineteen Bog Grass Moths were collected in a single night's survey.
- The fen's sedge plants are the only food for the moth larvae.
A significant discovery has been made in north Wales with the identification of the rare Bog Grass Moth at Cors Geirch National Nature Reserve. This finding occurred during a species survey conducted by conservationists on the Llŷn Peninsula in Gwynedd. Experts described the find as a "special surprise" for the "incredibly sparse moth."
The moth's presence is linked to the fen habitat, which supports the growth of wet sedges, the only food source for the Bog Grass Moth's larvae. This discovery underscores the ecological value of Cors Geirch, a site monitored by the Natur am Byth's Llŷn and Ynys Môn project, dedicated to safeguarding at-risk species.
During a recent survey, moth traps revealed 19 Bog Grass Moths among a total of 446 moths from 91 species collected in one night. This marks the first recorded instance of the Bog Grass Moth in this specific area. Other rare species noted at the reserve include the Six Spotted Crane Fly and the Black Nightrunner Ground Beetle.
Conservationists emphasize that such discoveries highlight the importance of targeted surveys in specialized fen habitats. These wetlands, crucial for rare species, have faced challenges due to habitat loss. Protecting and managing these peatlands is vital for biodiversity and for their role in carbon storage.
