Horsehair Worms (roundworms).

Description:

Horsehair roundworms are worms that are very thin and can sometimes look transparent or brown like hair. They are parasites of birds and live inside some insects such as grasshoppers. They can be found around water or anything where there is moisture and under damp fallen leaves and soil. They are active during summer and fall. These roundworms are not harmful to humans or domestic animals. They are beneficial because they can help control cricket or grasshopper populations.

Habitat:

Soil, under damp leaves.

Notes:

Found at the Natchez Trace around Clinton, MS under leaves.
