Morley’s Final Catalogue: Doubtless abundant on birch everywhere. Both sexes observed only about Ipswich (Freeman) in Bentley Woods during May 1898-1934 & Foxhall; in Blythburgh Wood in June (Mly); and at Southwold (Ctw).
Recent Status: Uncommon in Suffolk.
Life Style: A single brooded species that comes to light during April, May and June. The larvae feed on Betula and Alnus. They initially feed inside a twig resulting in a stem gall. Later they create a retreat by folding over a leaf edge. They pupate in a cocoon on the ground where they pass the winter.
Identification: A relatively large species of Epinotia that is variably marked. The forewing is usually a shade of brown. There are paler areas on the dorsum at the base, at one half and at the tornus. These patches are not always clearly marked but the central dorsal mark has the straight anterior edge set at right angles to the dorsum. More Info
