Morley’s Final Catalogue: Frequent in Bentley Woods (Pyett), Frostenden, Foxhall, Aspall (Mly), Bramford and elsewhere round Ipswich; Fritton, on Gorleston palings, &c. On oak, bred Thetford, &c. (Whit).
Recent Status: Seemingly less common that in Morley’s time.
Life Style: A double brooded species that has been recorded from April to September. The larvae feed on deciduous Quercus species. They pupate in the larval habitation. The pupal stage passes the winter.
Identification: The moth is similar to a weakly marked P. messaniella except that it lacks the extension from the second dorsal mark to the apex of the third marks. There is sometimes a dark suffusion along the middle of the wing between these marks but that does not emanate from a curved dorsal mark. The larval blister mine is usually on the underside of a leaf and shows a single crease in the lower epidermis. The species can only be identified from the summer mine where the cocoon is completely covered in frass. The pupae can be identified. MBGBI Vol 2 should be referred to for this purpose. More Info
