Morley’s Final Catalogue: Very frequent with us wherever copper or ordinary beech occurs. Tattingstone, Ipswich, Bramford (Mly); Dunwich, Minsmere, &c bred (Whit.); Glemham Magna (Bloomf.); Leiston (Grey).

Recent Status: A common Suffolk species.

Life Style: A double brooded species that has been found from April to September. The larvae feed on Fagus. They pupate in a cocoon in the larval habitation. The pupal stage passes the winter.

Identification: The adult moth shows a classic Phyllonorycter patterning. The ground colour is a golden to dull ochreous brown. There are four costal and three dorsal black edged white marks. The third dorsal is usually very small. The basal streak is broad, straight and not normally dark edged. They are similar to a number of other Phyllonorycter species and require genitalia dissection for identification.
The larvae create a white blister blotch on the underside of a leaf that usually runs between two veins and from the mid-vein to the leaf edge or close to it. The upper surface is bowed up and the lower epidermis constricted with a large number of ridges often appearing as one. More Info
