The birch sickle- winged wing ( Falcaria lacertinaria ) is a butterfly from the family of the owl moth and sickle-winged winged (Drepanidae).

features

The moths reach a wingspan of 27 to 35 millimeters. The forewings of the two generations occurring in the same year differ in color. The first has dark front wings with white highlights and restless markings, those of the second are evenly yellow-brown. In the middle of the wings of both generations there are two parallel, brown transverse lines. The outer edge of the forewings is unevenly fringed. The hind wings are light colored, only on the outer edge with a dark brown line.

Occurrence

They occur almost everywhere in Europe , northwards to Lapland . They live where birches ( Betula ) grow, such as in heaths and moors with birch stands and prefer sunny areas with high humidity. But you can also find them in damp places with alder stocks .

Way of life

They fly in two overlapping generations from April to the end of August.

Flight and caterpillar times

The moths fly in two generations from late April to early June and from July to late August. The caterpillars from the eggs of the first generation are found in September, those of the second in June of the following year.

Food of the caterpillars

The caterpillars feed on leaves of birch trees ( Betula ) such as B. Bog birch ( Betula pubescens ) and silver birch ( Betula pendula ), but also of black alder ( Alnus glutinosa ).

development

The caterpillars spin into a leaf to pupate. They hibernate on the ground before they hatch as butterflies.
