Key Identification Features:
Flight Period: End of August to early November.
Status: Widespread throughout north Armagh and Down but much more local in other counties. There have been no recent records north of Lough Neagh.
Ecology: An autumnal species found mainly in deciduous woodland and old estates. Adults appear at light in very small numbers. It has also been documented that they often visit Ivy Hedera helix blossom and overripe berries. Adults have never been found by day in N. Ireland but they probably conceal themselves among ground vegetation. The larvae feed from April to June on Wych Elm Ulmus glabra, poplar Populus spp. and Ash Fraxinus excelsior. It overwinters as an egg.
World Distribution: Throughout western Europe to central Scandinavia and Finland.
