Leaf-miner/Leaf-spinner: Numerous, short, narrow galleries, mainly in the basal half of the leaf. Frass in a central interrupted line. The older larvae live free under a communal web (Bladmineerders van Europa).
The larvae initially mine the leaves, making narrow galleries and then feed gregariously in a slight web (British
leafminers).
Larva: The larva is illustrated in Bladmineerders van Europa and British
leafminers.
Pupa: See Patočka (1997a), Patočka & Turčáni (2005a) (Bladmineerders van Europa).
Adult:
The adult is illustrated in UKMoths. The species is included in mothdissection.co.uk.

Time
of year - larvae: June-July; September-October (British
leafminers). Larvae in June-July and September - October (Agassiz, 1996a), but only the young larvae of the first generation do mine (Hering, 1957a) (Bladmineerders van Europa).
Time
of year - adults:There are two generations, adult moths being on the wing in April and May, and again in August. The moth can be taken at light (UKMoths).
