Lasioptera vitis

Osten Sacken, 1862

Grapevine Tomato Gall Fly

Lasioptera vitis is a of gall midge in the Cecidomyiidae, commonly known as the Grapevine Tomato Gall Fly. The species is associated with grapevines (Vitis spp.), as indicated by its specific epithet. Like other members of the Lasioptera, it likely induces gall formation on plants, though specific details about the of its galls remain poorly documented in accessible literature.

Taxonomic note

The was described by Osten Sacken in 1862. The Lasioptera is taxonomically challenging, with many species poorly known and difficult to identify without specialized expertise.

Data limitations

Available sources provide minimal biological information beyond taxonomic placement and association. Detailed studies of , gall , and economic significance appear lacking in accessible literature.
