Host plants:
The larvae are polyphagous. In the Spanish Monegros I recorded mature larvae especially on yellowish flowering Asteraceae (Sonchus, Crepis).

Habitat:
Ocnogyna boeticum usually inhabits dry and warm places from the coast to medium-high mountains.

Life cycle:
In the South, the moths mainly occur in November and December, further to the North more between January and March. The larvae develop between winter and spring. In the Monegros (Ebro depression), presumably the northernmost site in Spain, I recorded mature larvae in late May 2018. The younger larvae live gregariously in webbings near the ground. In the penultimate and especially last instar they live singly.

Remarks:
Ocnogyna boeticum occurs in N-Africa, the Iberian Peninsula (to the North up to Zaragoza), in Sicily and very locally in the southern half of mainland Italy.
