Pontomyia is a genus of flightless marine midges belonging to the subfamily Chironominae in the Chironomidae family.

Algae attached to sea turtles have been found carrying Pontomyia larvae and this form of hitch-hiking can potentially serve as means of dispersion.

[2][3][4] P. natans is widely distributed around the Indian and Pacific Oceans and its life history is slightly better known than other species.

The adults live less than three hours long with males dying shortly after mating and females after laying eggs.

Adult emergence is linked to lunar cycles, mainly at low tide, and midges are attracted to lights.
