Morley’s Final Catalogue: Causes swellings in willow-shoots; imagines rarely observed. Beaten from bushes in Raydon Wood during May 1933, only once flew to light at Monks Soham (Mly); one example taken at Ampton during 1911-2 (Nurse, Ent. 1913, 195).
Recent Status: A rare species in Suffolk.
Life Style: The moth is single brooded flying during May and June. The larvae feed on the pith of twigs of Salix cinerea and S. caprea. They hibernate in a cocoon in the larval habitation in which they pupate in spring.
Identification: The moth is white or cream. The head, thorax and an irregular basal patch are grey with darker patches. The terminal quarter is marked with grey and light brown with plumbeous stria and includes variable sometimes strong black marks in the ocellar area. The main wing area bears variable clouding of grey and light brown. The feeding of the larvae results in a slight swelling of the stem (slender gall). Prior to hibernation the larvae will cut an escape hole for the adult just above a bud which is silk covered. More Info
