Stibasoma

Stibasoma is a genus of flies belonging to the family Xylomyidae, commonly known as xylomyid flies or wood soldier flies. These flies are distributed globally, with species found in various regions, including Europe, North America, and Asia.

Stibasoma flies are generally characterized by their slender bodies, often with a dark coloration and distinctive wing venation. They are typically found in wooded habitats, where their larvae develop. The larvae are saprophagous, meaning they feed on decaying organic matter, particularly in rotting wood. Adult Stibasoma flies are often observed resting on vegetation or near decaying wood.

The specific identification of Stibasoma species can be challenging, often requiring examination of detailed morphological features, such as the structure of the antennae, wing veins, and genitalia. Taxonomic classification within the genus has been subject to revisions over time, and the exact number of valid species is continually assessed by entomologists. Further research and taxonomic studies continue to clarify the relationships and distribution of Stibasoma species worldwide.
