Possibly the same species as the European Freraea gagatea.
Explanation of Names
The species was first found in the White Mountains of New Hampshire.
About 4 mm
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.
Widespread in boreal and montane regions of North America. Range and habitat probably are the same as the host species.
The only known host is the ground beetle Amara quenseli.(1) The European species is also a parasite of adult Amara.
