Size
About 4 mm
Identification
Once identified as Tachinidae, it is very distinctive with the gradually convergent R4+5 and M veins, nearly bare body, and dark, shining color with dark wings. It was previously placed in subfamily Phasiinae with other bare species, but genital characters suggest it belongs to Dexiinae.
Range
Widespread in boreal and montane regions of North America. Range and habitat probably are the same as the host species.
Food
The only known host is the ground beetle Amara quenseli.(1) The European species is also a parasite of adult Amara.
