Opomyzoidea

The Opomyzoidea are a superfamily of flies.

Biology
Opomyzoids show a range of lifestyles including mining plant leaves (many Agromyzidae), feeding in grass stems (Anthomyzidae and Opomyzidae), forming plant galls (Fergusonina), feeding on fungi (some Anthomyzidae and Asteiidae), feeding on sap flows of trees (some Aulacigastridae, Odiniidae and Periscelididae), living in galleries of wood-boring insects (Odiniidae) or in water-filled cavities of plants (phytotelmata; Aulacigastridae, Neurochaetidae and Periscelididae). However, the biology of most opomyzoid families is poorly known.

Phylogeny
The phylogeny of Opomyzoidea is controversial, with different authors assigning different families and different relationships among families. One study using molecular analysis concluded that the superfamily is not monophyletic.
