Morley’s Final Catalogue: Abundant everywhere on elm; unnoted in the west. Copdock, Bramford, Nacton, Hacheston and Marlesford, Aldeburgh, Leiston, Yoxford, Blythbro Wood, &c.

Recent Status: Locally common in Suffolk.

Life Style: A single brooded species flying from June till September. The larvae feed on Ulmus and Acer campestre. They pupate on the ground. The ova pass the winter.

Identification: The moth is very variable. When specimens show markings then the shape and clearly marked edge of the basal patch should allow identification. Otherwise genitalia dissection may be necessary.
The larvae feed in unopened buds in their first instar that results in a characteristic arc of holes between the veins as the leaves open and expand later in the year. More Info
