02Description

Species Profile

Species profile data sourced from the IUCN Red List of Threatened Species.

The Moorland Clouded Yellow faces severe population declines due to habitat loss from agricultural intensification, peat bog drainage, and climate change impacts on its specialized moorland ecosystems. Rising temperatures and altered precipitation patterns are shifting suitable habitat ranges northward and to higher elevations, while remaining populations become increasingly fragmented and isolated.

Key Facts

IUCN StatusCritically Endangered (CR)
GroupInsects
03Habitat

Habitat & Distribution

Inhabits acidic peat bogs, wet moorlands, and montane grasslands typically above 400m elevation, particularly areas with abundant bilberry and bog bilberry which serve as larval host plants. Requires cool, humid conditions with specific microclimatic requirements including morning dew and shelter from strong winds.
