Once widespread, this very rare species has not been seen in Belgium for a long time. Discovered again in 2023 in BW with a healthy population.
Native
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.
The adults are on the wing from June towards mid-August.
Caterpillars are nocturnal in flowers of Campanula species, preferably Campanula rotundifolia.
