Drepanidae » Drepaninae
The largest and commonest of the 'hook-tips',
Wingspan male 36-40 mm, female 40-43 mm. In Scotland moths are distinctly straw-coloured with outer markings darker (ssp. scotica), elsewhere, occasional individuals can be very pale (f. pallida), but only likely to be confused with Dusky Hook-tip D. curvatula, a rare immigrant from Europe, which is darker and has the three discal spots roughly the same size (in falcataria, the outer discal spot is much larger then the other two).
The adults fly at night from May to June and have a second brood in August.
The larvae feed usually on birch (Betula), but sometimes on alder (Alnus glutinosa).Common in woodland, especially of birch, heathland and gardens throughout Britain.
