The owl moth ( Tethea ocularis ) is a butterfly from the family of the owl moth and sickle winged moth (Drepanidae).
features
The moths reach a wingspan of 32 to 38 millimeters. They have gray-brown or gray-black forewings with a broad, light-colored transverse band in the middle. This is bordered on both sides by two black thin cross ties. On the edge of the light transverse band there is a round and a light spot similar to an “8” with a dark core.
The caterpillars are about 40 millimeters long. They are whitish-green with age and have a brown head that is flattened. They have very faint dark markings and a black dot on the first segment on the side. The young caterpillars have more distinct dark markings.

Occurrence
They occur in southern and central Europe east to Japan in warm and humid deciduous forests with poplar stands , especially in alluvial forests , streams and river valleys but also in parks. They are absent in the north of Scandinavia and Great Britain . The species is very sensitive from an ecological point of view and places high demands on the biocenosis. Therefore their occurrence is quite local and reduced to species-rich biocenoses with less intensive forms of cultivation.
Way of life
The animals are nocturnal and can only be easily attracted by artificial light after midnight.
Flight and caterpillar times
The moths fly in two generations from early May to early July and from mid-July to mid-August. The caterpillars from the eggs of the first generation are found from August to September, those of the second from July to September of the following year.
Food of the caterpillars
The caterpillars feed on the leaves of the quaking aspen ( Populus tremula ) and other poplar species ( Populus ).
development
The females lay their eggs in small groups on leaves. They cover them and the surrounding surface of the leaf with scales. During the day, the nocturnal caterpillars hide between two leaves that are spun together. They pupate on the ground between dry leaves in a loose web and only hatch after winter.
