Gypsonoma dealbana

(Frölich, 1828)1169 / 49.279

Morley’s Final Catalogue: Very common, though not in the south English profusion. Bentley, Staverton Thicks, on lime trunks at Monks Soham garden and Glemham Magna to Gorleston and Brandon.

Recent Status: A common species in Suffolk.

Life Style: A single brooded species that comes to light. It can be found from May till October.. The larvae feed on Crataegus, Quercus, Populus, Corylus, Salix and Acer pseudoplanatus. Prior to hibernation they graze from a web beneath a leaf. They enter a stem for hibernation where they continue feeding after hibernation and then from spun leaves or in catkins. They pupate in a cocoon on the ground.

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 usually 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
