Leaf-mine:
The initial mine is like that of a nepticulid. The case is made
form excised leaf portions, which are added to the oral end, leading
to the ringed appearance. The larva causes the leaf to have white
blotches. Identification cannot be made on these alone as similar
blotches can be made by early instar larvae of the Common Blue butterfly
(Polyommatus icarus) (British
leafminers). The case is also illustrated in UKMoths.
