Phantom Midges resemble mosquitoes (family Culicidae) or non-biting midges (family Chironomidae), but differ in lacking the proboscis of the former and the divided subscutellum of the latter. The larvae are transparent (hence the common name), and have modified antennae with which they grab prey. They are able to control their buoyancy, hanging in the water column as sit-and-wait predators.
