Phyllonorycter strigulatella

(Lienig & Zeller, 1846)344 / 15.066

Morley’s Final Catalogue: Not listed.

Recent Status: A rare species in Suffolk.

Life Style: A double brooded species that has been found during May, July and August. The larvae feed on Alnus incana and occasionally on Alnus glutinosa. They pupate in a silk lined chamber in the larval habitation. The pupal stage passes the winter.

Identification: The moth is easily identified having a distinctive patterning of black edged white marks on a bright orange brown forewing. The forewing is also dark edged between the marks. There are two large triangular dorsal marks and a long, broad, blunt ended mark on the costa between them. A further three costal and one or two dorsal marks beyond are less strident. There is a basal streak and basal dorsal mark. A strong black terminal mark is pale beyond.
The larvae create long narrow blister blotches between veins with small creases on a constricted lower epidermis. The upper surface is mottled by feeding on the parenchyma. There can be more than one per leaf. More Info
