Leaf-miner: The young larva makes one of, more probably, several tiny mines, from which much of the frass is ejected. Part of the frass grains are trapped in a slight spinning under the mine (Bladmineerders van Europa).
The initial mine is small. The larva then feeds mostly on the upper surface of the leaf, under a slight web (British
leafminers).
Larva:The free living larva is light or dark greyish green with three darker length lines. The lara lives under a slight spinning at the upperside of the leaf, casuing window feeding (Bladmineerders van Europa).
The young larva is green but it changes colour as it matures. The final instar larva is darker green dorsally with yellow-green blocks on its side and subdorsally (British
leafminers).
The larva is illustrated in UKMoths and British
leafminers.
