Scientific name: Watsonalla binaria

Two generations from May to June and late July to mid-September. Common and well distributed as far north as Cumbria. Quite a distinctive orange-brown moth which rests with its broad wings held flat.

The forewings have two well-defined pale cross-lines and two blackish spots in the centre. The males are often darker and smaller than the female. The males can occasionally be seen flying high around oak trees.

The larvae can be seen from June to July and late August to September which then overwinter as pupae in a tough brown cocoon which is spun inside a tightly folded oak leaf.
