Facts About Flesh flies

Flesh flies depend on dead or live tissue to complete their life cycle. These pests go through the egg, larva, pupa, and adult stages.

The eggs incubate, develop, and hatch inside the adult’s body or near carcasses instead of external food sources. Once the eggs hatch, the female deposits larvae into decomposing flesh, manure, or other suitable areas.

Each species prefers different sources and decomposition stages to deposit the larvae. Nevertheless, the female chooses the laying site that has plenty of food to complete the lifecycle. Larvae feed for four days.

A female can produce hundreds of eggs in her lifetime. Some common developmental sites include inside animal carcasses, decaying meat garbage.

The flies pupate after completing the larval stage. The pupae can remain dormant for weeks, but some species take up to 15 days. Once the larvae are ready to pupate, they wander to find a favorable location.

An adult is the same size as a housefly once they complete the lifecycle. They have a red body portion on their abdomen, red eyes, and transparent wings. The lifespan of these flies may extend up to 21 days, depending on conditions and species.
