Xylomya aterrima
Johnson, 1903
Xylomya aterrima is a of wood soldier fly in the Xylomyidae. It belongs to a small family of flies whose larvae develop in decaying wood and under bark. The species was described by Johnson in 1903. Like other members of its , it is likely associated with forested where dead and decaying wood is present. The family Xylomyidae is closely related to Stratiomyidae and shares ecological similarities in larval development.

Identification
Xylomya aterrima can be distinguished from other Xylomyidae by its uniformly dark (aterrima derives from Latin for 'very black') coloration. The Xylomya is characterized by a reduced anal lobe in the hind wing and specific wing venation patterns. -level identification within Xylomya requires examination of genitalia and other fine morphological details. Separation from similar dark-colored Diptera such as some Stratiomyidae or Xylophagidae requires attention to wing venation, specifically the presence of a distinct anal and the structure of the .
Habitat
Associated with forested environments containing dead and decaying wood, which provides larval development sites.
Distribution
North America. The has been recorded in the United States based on collection records and observations.
Ecological Role
Larvae are saproxylic, contributing to wood decomposition and nutrient cycling in forest . The is considered a minor component of the dead wood .
Human Relevance
No direct economic importance. Not a pest . Of interest to entomologists studying saproxylic insect and Diptera .
