- Exaireta siliacea
- Exaireta spinigera
Exaireta is a genus of distictive, elongate, blackish soldier flies. Adults of Exaireta spinigera are collected by sweeping, at lights, and in malaise traps (Woodley 1995). They are often seen at flowers or near rotting vegetation. Larval Exaireta live in a range of decayig organic matter, including rotten potatoes, sugarcane, and wounds on tree trunks. E. silacea is seldom collected.
These flies are native to Australia, Tasmania and New Zealand. E. spinigera is a widespread and common introduced species in Hawaii (Woodley 1995). More recently, E. spinigera has become established in California and British Columbia (M. Hauser, pers. comm.; see Bugguide.net).
Exaireta is diagnosed by the presence of pilose setae on the subscutellum (Woodley 1995). They are large flies, from 8.5 to 16 mm.
