Scoliopteryx libatrix (Linnaeus, 1758)

Host plants:
The larvae feed on Salix and Populus species.

Habitat:
Scoliopteryx libatrix inhabits softwood rich wooded areas of all kinds from woodlands to the human settlement area.

Life cycle:
Scoliopteryx libatrix flies mostly in two, sometimes even three generations per year. The adults hibernate in cavities, sheds, caves and similar places. The eggs are usually deposited singly on the lower sides of the young leaves near the shoot tips. The caterpillars mainly live in May and June and again from July to September on young leaves. They rest openly on the leaves (midrib) or twigs (usually shoot tip).

Remarks:
Scoliopteryx libatrix is widespread Holarctic. It is therefore also present in North America. In central Europe it is one of the most regular species, but occurs in southern Europe usually only in more humid mountain ranges.
