[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.

The genera Glutops and Pseudoerinna are distributed in the Nearctic and eastern Palaearctic.
