mine

Oviposition in the very leaf tip. From there a very deep upper surface blotch extends downwards. The blotch, that is very transparant, can occupy a large part of the leaf. Mostly the entire width of the leaf is mined out, but the broad leaves of the Goat Willow are mined at one side of the midrib only. Pupation within the mine in a large, transparant, discoidal coccoon.

hostplants

synonyms

Phyllotoma microcephala.

notes

Very young mines are still shallow and opaque, and can strongly resemble those of Agromyza albitarsis. The larvae of that species are maggots, and its mines are not associated with the leaf tip.

The lower picture above is unusual because the mine did not start at the utter leaf tip. (Two other mines of the same sample were normal.)
