Archaeodromus anglicus was a small archaic member of Strisores, the wider radiation that includes nightjars, potoos, swifts and hummingbirds. It belonged to Archaeotrogonidae, an extinct lineage that combined a generally strisorean skeleton with proportions unlike any living nightbird.

Its ecology is not directly preserved, but the anatomy is consistent with a volant small bird that probably took insects and other small prey. The London Clay material is mainly skeletal rather than plumage or gut content, so aerial or perch based insect feeding should be treated as a well grounded inference rather than direct evidence.
