What do biting midge eggs look like?

The Anatomy of Biting Midges

Mom midges lay up to 110 white eggs that turn brown or even black before hatching, which only takes 2-10 days. They like to mate off in the wild, but keep an eye out for the eggs. The larvae are worm-like and white before growing into pupal that range from yellowish to dark brown in color.

Do midges lay eggs?

Adult females lay their eggs in the water or on the margins of water. The eggs hatch into free-living larvae which go through several moults before they pupate. The adult emerges and sits on its empty case for a moment to open its wings before buzzing off.
