[2] On emerging from their host larvae, these nematodes fall to the bottom of the water body.

The eggs hatch after four weeks and each preparasitic larva searches for a suitable host; it will die if it does not find one within seventy-two hours.

It bores a hole through the cuticle of the host mosquito larva with a stylet, and develops in its body cavity.

When ready to leave the mosquito larva, it bores a larger hole through which it emerges.

The mosquito larva does not survive because its body fluids leak out through the hole.
