Ocnogyna zoraida (Graslin, [1837])

Host plants:
The larvae are polyphagous in the herb layer. I found a few larvae feeding in an inflorescence of a pad-like Artemisia species.

Habitat:
Ocnogyna zoraida inhabits nutrient-poor grasslands and pastures, mountain slopes and rocky areas.

Life cycle:
The moths are on the wing between April and early August (according to altitude). Oviposition usually occurs in one large, loose batch. The larvae occur between May and early September. They are usually mature in medium-high altitudes in July. They are most often active at night, but sometimes - especially in hot weather - also during daytime. I recorded the mature larvae often crossing streets, partly also feeding. The pupa hibernates.

Remarks:
Ocnogyna zoraida is mostly restricted to the Iberian Peninsula, but misses there in the northwestern part. It just reaches France in the eastern Pyrenees.
