The Glamorgan Moth Group are a group of local moth enthusiasts devoted to the study and conservation of moths within the Vice County of Glamorgan, in south Wales.
Species account from Moths of Glamorgan (Gilmore, Slade & Stewart, 2009):
Univoltine, flying from mid November to early January. Recorded from Swansea/Gower Peninsula and the Cardiff District. Eight of the nine records relate to adults, the other is of three larvae in May 1997. It may be overlooked due to its flight period, and its similarity to the much commoner Winter Moth (Operophtera brumata).
