Gypsonoma aceriana

(Duponchel, 1843)1167 / 49.283

Morley’s Final Catalogue: Fairly common among poplar, and on tree-trunks in woods. Frequent in Bentley Woods (Hkg, Pyett); Ipswich in 1930-1 (Whit); Leiston (Grey); Lowestoft (Bd); Brandon (Barrett).

Recent Status: One of the less commonly recorded Gypsonoma species. Possibly under-recorded.

Life Style: A single brooded species flying at the end of day and occasionally coming to light from June to August. The larvae feed inside twigs of Populus species. They pupate away from the larval habitation in a cocoon.

Identification: There are three similar species of Gypsonoma, G. dealbana, G. sociana and G. aceriana. G. aceriana is the least marked species and has the edge of the dark basal patch almost straight which character separates it from similar Olethreutinae. It may show a few black scales in the ocellus and have a slightly darker suffusion mid termen and through the central area to the triangular but weakly marked pre-tornal spot. It has a dark head and palps. G. sociana has a strongly marked pre-tornal spot and a prominent dark mark from the costa at one half. It has a white face but dark crown and the dark palps are white tipped. G. dealbana has a strongly marked pre-tornal spot and a dark mark centrally in the wing just before and above the ocellus. It has a white face, a beige vertex and a brown crown. The palps are pale brown, white tipped. G. dealbana commonly shows much darker forms that the other species do not. More Info
