Host plants:
According to literature, the caterpillar lives polyphagous on herbs, but prefers Fabaceae such as Lotus, Hippocrepis and Coronilla.
Habitat:
Scotopteryx bipunctaria is most often found in nutrient-poor, stony grasslands and limestone juniper slopes.
Life cycle:
The moths fly in a single generation from July to early September (few individuals sometimes even sooner). The caterpillar overwinters.
Endangerment: endangered
Endangerment factors:
Scotopteryx bipunctaria is in decline due to loss of grasslands (eutrophication, abandonment and felting and bush encroachment, overbuilding, agricultural intensification). But it is still quite steady on remaining nutrient-poor grasslands.
Remarks:
The distribution extends from Morocco across Europe to the Caspian Sea.
