Amauromyza flavifrons

The leaf-mine formed by this species is found on the leaves of various plants including Campion. A short linear mine is formed, then a white blotch mine, the linear section sometimes is not visible under the blotch that is formed later. The blotch has a few small black grains of frass.

See the National Agromyzidae Recording Scheme webpage on this species for further details of larva, adult insect and host plants

Pegomya flavifrons [Anthomyiidae] can form very similar mines.
