mine

Essentially a corridor mine. It begins as a tiny upper-surface spiral. The corridor at this point is so narrow and closely wound that it rather resembles a simple spot. Next follows a simple corridor running towards the leaf tip, often following the leaf margin for some distance. In the leaf apex a quite long corridor is made, while the mine is laid in loops that are so close that a secondary blotch results, with prominent secondary feeding lines. The final section of the mine again is a simple corridor, in the end of which pupation takes place. Before pupating the larva already has made a semicircular slit in the epidermis. Not infrequently the puparium falls out (Hering, 1957a).

distribution within Europe

larva

Nowakowski (1959a).

notes

The frass pattern in this species is very unusual, because the frass is not deposited in two lines, as is the rule in Agromyzidae. Especially young mines therefore may easily been taken for the work of a beetle like Apteropeda.
