Diarsia dahlii (Hübner, [1813])

Host plants:
The larvae are polyphagous on herbs and dwarf shrubs.

Habitat:
Diarsia dahlii inhabits moors or at least wet habitats, most often in open forests.

Life cycle:
The moths occur in one generation between July and early September. The larva hibernates.

Endangerment factors:
Diarsia dahlii has become very rare in Central Europe. Besides habitat loss probably also climatic change play a role.

Remarks:
Diarsia dahlii occurs especially in Northern Europe and more northern parts of Asia to Japan. In Central Europe it is mainly found in mountain ranges and moor-rich landscapes.
