Host plants:
The larvae feed on willows and poplars.
Habitat:
Catocala electa inhabits river valleys with riparian forests, sea shores and other more warm sites rich in Salicaceae bushes and trees.
Life cycle:
Larvae feed between April and June or even July and are well camouflaged on twigs and trunks. Moths occur mainly between mid-July and September.
Endangerment factors:
Catocala electa is endangered in Central Europe because riparian forests have been destroyed except for small remnants in most regions.
Remarks:
Catocala electa occurs in Europe and temperate Asia to Japan.
