Leaf-mine: Blotch clouded, with some green matter left in mine. Several larvae (2-4) in one mine (British leafminers).

Large full depth blotch, adjacent to the leaf margin. The mine is not completely eaten out, which gives it a greenish or off-white appearance. Frass in threads, that seem to be somewhat shorter than in other Eriocrania's. The mine harbours 2-4 strikingly hyaline larvae. Pupation in the ground. Older mines wither and wear off; in summer no trace of them is left (Bladmineerders van Europa).

The mine is also illustrated in UKMoths.

Larva: Small, translucent white (British leafminers).

The larva is illustrated in Bladmineerders van Europa.

Pupa: Details unknown.

Adults: The adult is illustrated in UKMoths. The male and female genitalia are illustrated by the Lepidoptera Dissection Group.

Hosts elsewhere:

Time of year - larvae: May (British leafminers).

Time of year - adults: The adults fly around the foodplants during April, but are not often seen (UKMoths).

Distribution in Great Britain and Ireland: Generally well distributed throughout much of mainland Britain (UKMoths) including Bedfordshire, Buckinghamshire, Derbyshire, East Kent, East Suffolk, East Sutherland, Glamorgan, Herefordshire, North Essex, North Hampshire, Shropshire, South Wiltshire, Stafford, Surrey, Warwickshire, West Gloucestershire, West Kent, West Norfolk, West Suffolk, Westmorland and Worcestershire (NBN Gateway - N.B. includes Watsonian Vice Counties having publicly available records that fall within or overlap the vice county border at 10km resolution or better i.e. a record for a vice county may relate to an adjacent vice county - for included datasets see NBN Grid map below).

Also recorded in the Republic of Ireland (Karsholt and van Nieukerken in Fauna Europaea).
