Morley’s Final Catalogue: Common at Ipswich in 1897 (Pyett) and bred there in 1932-4 (Whit.); Orford in July 1902 (Gibbs); Aldeburgh (Ctw); Leiston, Glemham Magna, Lowestoft. Gorleston, Benhall and Parham wood during May (Mly).
Recent Status: A common Suffolk species.
Life Style: The species is double brooded and has been recorded from April to October. The larvae feed on leaves of rosaceous trees including Malus, Crataegus, Pyrus and Sorbus. They pupate in a cocoon in the larval habitation. The pupal stage passes the winter.
Identification: The adult moth is characteristically marked and cannot be confused. The larvae create blotch on the upper surface over the mid or a side vein. The blotch is a double mine. A small darker mine created by early instar larvae is visible with it. The later blotch with dispersed frass eventually becomes a blister causing the leaf to fold upwards. More Info
