larva

The larvae among the species are aquatic, living among dense vegetation in wetlands, while the adults fly from spring until early August.

Symptoms can include painful skin sores or wounds that may not heal, the feeling of the larvae moving, or a foul-smelling odor, the CDC says.

These include unexplained skin lesions, feeling larvae move within a wound or the nose, mouth or eyes and seeing maggots in an open sore.

Hatchery operators say they've significantly reduced shrimp larvae production as a result.

NWS myiasis is a parasitic infestation of fly larvae, or maggots, caused by parasitic flies.
