Freshwater environments like streams, ponds, and puddles, but also found in damp soil

Diet & Feeding

As larvae, they are parasites of arthropods like grasshoppers, crickets, and beetles. Adults do not eat.

The larvae live inside a host's body. Once mature, they influence the host's behavior to seek water, where the adult worm emerges to mate.

Risks & Benefits

They are harmless to humans, pets, and plants. They benefit ecosystems by controlling insect populations naturally.
