The cliff swallow bug Oeciacus vicarius (Hemiptera: Cimicidae) in Florida: ectoparasite implications for hole-nesting...

In May 1988, ten juvenile birds, not yet ready to fledge, jumped to their death from a colony of the purple martin, Progne subis near Okeechobee City, Florida. The martin house and nestlings were found to be infested with ectoparasitic Oeciacus vicarius Horvath, the cliff swallow bug, not previously reported from Florida. This ectoparasite infestation apparently led to early abandonment of two houses by the adult martins. Oeciacus vicarius therefore represents a possible threat to all hole-nesting birds.
