Pelecorhynchidae is a small family of flies. All of the genera were originally placed in the family Rhagionidae, and their elevation to family rank has been controversial.[5] Other phylogenetic analyses have supported Pelecorhynchidae as a distinct clade from Rhagionidae.[6] The adults of Pelecorhynchus mostly feed on nectar of Leptospermum flowers. Larvae have been collected in the damp margins of swamp areas, where they feed on earthworms.[7]
