Xylomyidae

Definition

A family of true flies (Diptera) in the infraorder Stratiomyomorpha, commonly called wood soldier flies. Larvae are xylophagous, developing in dead or decaying wood where they contribute to nutrient cycling and wood decomposition. Adults are typically found in forested habitats near larval substrates.

Etymology

From the type genus Xylomya (Greek xylon 'wood' + myia 'fly') + -idae (family suffix).

Example

Larvae of Xylomya species tunnel through punky heartwood of fallen hardwoods, while the smaller Solva pallipes often colonizes decaying branches in temperate riparian forests.

Synonyms

• wood soldier flies

Usage Notes

Distinguished from the related soldier fly family Stratiomyidae by larval habitat specificity (dead wood vs. diverse decaying organic matter) and adult morphology. The family is relatively small (~150 described species) and taxonomically stable. Checklist and phylogenetic placement within Stratiomyomorpha follows contemporary dipteran systematics.
