Caterpillar


Bionomics

Caterpillars live from July to September and initially eat flowers, but later they need seed capsules as food and morning dew as liquid. It hibernates as a pupa. In contrast to the caterpillars, the adults are sensitive to heat. During their main flight period, temperatures are high on the rocks, during the day, resting adults are therefore always found in deep shade, often hidden far in crevices or behind ledges. The adults are active at dusk and later come to light.


Flight periods

The adults are on the wing from June towards mid-August.
