The oak sickle-winged or two-point sickle-winged wing ( Watsonalla binaria ) is a butterfly from the family of the owl moth and sickle-winged wing (Drepanidae).
features
The moths are very similar to the beech sickle winged ( Watsonalla cultraria ) and also have a yellow-brown color. The clearest distinguishing feature are two black twin points on each of the forewings. Sometimes these appear weaker on the hind wings. The forewings have two lighter colored bars, the hind wings are colored the same as the forewings in the males, but in the females they are a little lighter in color. The adults of the second generation are much smaller and slightly lighter in color than those of the first.

Occurrence
The moths occur in North Africa , South and Central Europe in dry to slightly moist mixed deciduous forests such as oak-hornbeam forests , in alluvial forests , forests in river valleys and other mixed oak forests.
Way of life
On hot days the males can fly high.
Flight and caterpillar times
There are two generations per year. The first flies from late April to June, the second from late July to August. The caterpillars from the eggs of the first generation are found in September, the second from June to July of the following year.
Food of the caterpillars
The caterpillars usually live on oak ( Quercus ), especially English oak ( Quercus robur ) and sessile oak ( Quercus petraea ), which grow in warm locations. But they have also been found on beeches , birches and alders .
development
The females lay the eggs on the leaf margins of bushy food plants. The caterpillars that hatch from it live mainly on low-hanging branches. They pupate in a spun leaf and overwinter on the forest floor as a pupa .
