Where it lives

Typical habitats
  • compost piles
  • livestock facilities
  • dumpsters and waste sites
Range
It is common through much of the continental United States and occurs across the Western Hemisphere.
Preferred conditions

Behavior

Diet
Larvae consume decaying plant matter, food scraps, manure, and dead animals.
Activity
Adults lack a stinger and rely heavily on energy stored during the larval stage.

Life cycle

Reproduction
A female places a cluster of about 500 eggs in cracks near decaying material. The eggs hatch in about four days under warm conditions.
Larva
Larvae pass through six growth stages and can reach about 1 in (27 mm). Mature larvae leave the wet feeding site for a dry, sheltered place to .
