OpomyzoideaThe Opomyzoidea are a superfamily of flies.BiologyOpomyzoids show a range of lifestyles including mining plant leaves, feeding in grass stems, forming plant galls, feeding on fungi, feeding on sap flows of trees, living in galleries of wood-boring insects or in water-filled cavities of plants. However, the biology of most opomyzoid families is poorly known.PhylogenyThe 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.
