Morley’s Final Catalogue: Rather a local species. Found near Barham once in September (Steph. Illust. 1834, p. 199). Southwold, in 1897 (Ctw.); Felixstow, at sugar (Gibbs).
Recent Status: One of the commoner of the less frequent Depressaria species in Suffolk. Predominantly found in the Sandlings area.
Life Style: A single brooded species that flies from July till October and comes to light. The larvae feed on Hypochaeris radicata, Sonchus arvensis and Taraxacum. The larvae hibernate and pupate during mid-summer in a cocoon.
Identification: The moth is quite variable, some individuals are well marked and others may be almost devoid of markings. The actual markings do not vary and the moth has a dark patch at the base of the forewing that is always present. Head and thorax may often appear paler. The larvae initially feed between two spun leaves creating an obvious blotch. They later feed on the rootstock and hibernate and pupate in the ground alongside the root. More Info
