Drepana falcataria (Linnaeus, 1758)
Description: Wingspan 36-40mm. Adults are generally pale brown in colour with the characteristic hook-tip at the apex of the forewings. There is a small dark blotch near the centre of the forewing and a distinctive reddish brown line that runs from the apex of the forewing to the dorsum. The hind wings are similar in colour to the forewings and have a series of wavy lines.
Key Identification Features:
Flight Period: Late May until the end of August.
Status: Local, with the majority of recent records from cutover bogs in north Armagh, south Tyrone, central Down and SE Antrim. Reliable sites include Peatlands Park, the Argory, Lackan Bog and Rehaghy Mountain. Virtually unknown elsewhere.
Ecology: An elusive species that favours heaths and bogs particularly those with an abundance of birch. Despite sharing similar habitats with the Scalloped Hook-tip Falcaria lacertinaria this species is much less encountered. Adults are attracted to light but appear only sparingly. The larva feed on birch usually at night and rest on the underside of the leaves during the day. It spends the winter months in the pupal stage.
