Summary

Hylemya is a reduced genus of root-maggot flies within the family Anthomyiidae, primarily comprising a few North American species after the exclusion of subgenera and related genera. They are characterized by specific morphological traits and are commonly found in association with mammal dung.

Physical Characteristics

Arista with hairs as long as or longer than width of third antenna segment, katepisternal bristles 2:2, row of bristles across middle of tergites 4 and 5. Typical characteristics of Anthomyiidae include a normal proboscis, bare eyes, lower calypter not larger than upper, and well-developed presutural acrostichals (2+3 dorsocentrals).

Identification Tips

Identification can be facilitated by examining the length of arista hairs and the configuration of bristles on tergites.

Habitat

Widespread in North America, often found in areas populated by mammals where dung is available.

Distribution

North America, with at least two species recognized in the region.

Diet

Larvae are primarily associated with mammal dung, utilizing it as a breeding site.

Life Cycle

The life cycle includes a larval stage that develops in dung, particularly of deer and cattle.

Ecosystem Role

As decomposers, Hylemya larvae play a role in nutrient cycling by breaking down organic matter in dung.

Evolution

Formerly a much larger genus, now reduced primarily to North American species following taxonomic revisions.
