Gypsonoma oppressana

(Treitschke, 1835)


Wingspan c. 14mm.

A relatively local species, occurring sporadically throughout England, this moth flies during June and July in a single generation.

The larva feeds on poplar (Populus), initially grazing the underside of a leaf, from within a silken tube which becomes covered with frass.

The larva then overwinters, and in spring feeds internally on leaf buds. The presence of a larva can be established by a frass-covered silken tube protruding from the entrance hole to the bud.
