Penthetria
March flies
Penthetria is a genus of March flies (family Bibionidae) established by Meigen in 1803. Species in this genus have been documented in forest ecosystems, with at least one species, Penthetria holosericea, studied for its role in litter decomposition. The genus has a Holarctic distribution with records from Europe and North America. Males of some species exhibit brachypterous (shortened) wings.
