Host plants:
The caterpillar is polyphagous, but probably prefers Onobrychis and other Fabaceae.
Habitat:
Chlorissa viridata inhabits warm, wind protected grasslands in wooded area or with hedges. Besides, locally also Calluna heaths and fallen dry bogs are inhabited.
Life cycle:
According to literature the pupa hibernates. The moths fly depending on the altitude between late April or late May to early July, occasionally probably also in a partial second generation until August. The caterpillars might be expected from June to August or September.
Endangerment: endangered
Endangerment factors:
Chlorissa viridata has declined sharply due to the destruction of the nutrient-poor grasslands.
Remarks:
Chlorissa viridata occurs in Europe and temperate Asia.
