Natural Habitat

Found in soil, decaying organic matter, leaf litter, or near moisture where fly larvae complete their development.

Diet & Feeding

Does not feed during the pupal stage; larvae consume decaying organic matter, fungi, or animal/plant tissue.

Behavior Patterns

Immobile stage of complete metamorphosis where the insect transforms from a larva into an adult fly inside a hardened protective casing called a puparium.

Risks & Benefits

Generally harmless as pupae, though adult flies can be vectors for diseases or act as important decomposers and pollinators depending on the species.
