Leaf-mine: A gallery following the leaf-edge (British leafminers).

Egg generally at the upperside of the leaf, on a vein. The mine is a short corridor, no longer than 3 cm. Its first part is narrow and tends to follow a vein. The second part is rather tortuous and considerably widened, and often forms a secondary blotch. Generally only one mine in a leaf. Mines cannot reliably been distinguished from those of anomalella and centifoliella (Bladmineerders van Europa).

Larva: Amber yellow, head brown (whereas aenofasciella is a pale watery yellow) (British leafminers).

Dark yellow; the larva lacks a field of spinules at he rear of the pronotum, and on the mesosternum spinulation does not only occur on the rudiment of the foot, but also in two field obliquely in front. See Gustafsson and van Nieukerken (1990a) for a description (Bladmineerders van Europa).

Pupa: Details unknown.

Adult: Not illustrated in UKMoths (check for update). The genitalia are not illustrated by the Lepidoptera Dissection Group (check for update).

Distribution in Great Britain and Ireland: Britain including Bedfordshire, East Sutherland, Hertfordshire, North Hampshire and South Wiltshire (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). See also British leafminers distribution map.

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