Anthomyiidae
The Anthomyiidae belong, together with the Scatophagidae (and a number of families more, not relevant here) tot the superfamily Calyptratae or Muscoidea, characterised by the fact that the halteres, the remnants of the second pair of wings, are covered by a flap. The larvae of most species are phytophagous, but only a few are miners. Unlike Agromyzidae, the mining larvae lie dorsum-up in the the mine, creating a simple, central frass line. Often the frass liquifies, giving the mines a dirty appearance.
