Host plants:
The larvae feed on blackthorn.
Habitat:
Catocala fulminea inhabits areas rich in blackthorn, especially warm and air-humid scrub with Prunus spinosa in floodplains. On the other hand, it occurs only quite rarely in dry and hot habitats such as limestone grasslands with dwarf blackthorn. The exact habitat requirements are still not known in detail.
Life cycle:
The egg hibernates and is deposited on the trunks or on moss on the base of the trunks, but obviously at least partially on other, ground-near vegetation beween the stems of the host plants. The larva develops between April and May, only rarely still in early June. The moths occur between mid-June and August or even September.
Remarks:
Catocala fulminea occurs especially from N-Spain across France and Central and E-Europe to Russia. It usually misses in the Mediterranean bassin. In the Balkans it is found up to Bulgaria, but misses in more southerly Greece. There only C. hymenaea occurs on Prunus.
The oviposition places in the field of this and other Central European Catocala are only very recently better known by searching for eggs during winter time. Michael Levin (upper Rhine valley) has introduced this method very successfully and lets participate others in an altruistic way. Thanks for this! For most other less eagle-eyed people with a less sharp eagle eye.
