Identification
Bolbomyia can be distinguished from other snipe flies (Rhagionidae and related ) by its extremely small size (2–3.5 mm versus typically larger relatives) and lightly darkened wings. The combination of minute stature, brown to black coloration, and infuscate wing separates it from superficially similar Diptera.
Distribution
North temperate regions of North America, Japan, and the Russian Far East (including Kamchatka). The fossil B. loewi is known from Baltic amber.
