Leaf-mine: A linear track widens to blotch, frass in long threads (British leafminers). Corridor, generally starting not far from the midrib, at a conspicuous, yellowish oviposition scar, suddenly and somewhat angular widening into a full depth blotch. Often the corridor is overtaken by the blotch, but it remains recognisable in the frass pattern. Frass in long threads. Pupation in the ground (Bladmineerders van Europa). Mine of Eriocrania sparrmannella on Betula pendula Image: Willem Ellis (Bladmineerders van Europa) Larva: Larva white, gut-line green (British leafminers).
