Host plants:
The larva feeds on deciduous woods, especially on Oleaceae (Fraxinus, Ligustrum, Syringa) and Caprifoliaceae (Lonicera, Symphoricarpus, Weigela).
Habitat:
Apeira syringaria settles principally in forests which are rich in underwoods. Occasionally Apeira syringaria can be also found in gardens and parks.
Life cycle:
The caterpillar hibernates and is usually fully-grown in May. Pupation takes place in a light web at the bush. The moth is on the wing between June and July, in warmer regions already in late May and again in August/September in a partial second generation.
Endangerment: regionally endangered or decreasing
Endangerment factors:
Locally even this species is decreasing due to dark forest management.
Remarks:
Apeira syringaria occurs from Engalnd to Japan in the deciduous forest belt. In southernmost Europe Apeira syringaria is lacking.
