This larvae collected in Mexico City with characteristic snake-like motion is a member of the Ceratopogonidae family (biting midges). In some species, the larvae feed on microorganisms but most are predators of small to large invertebrates. Basically this larvae bite into the side of the prey, chew a hole through the cuticle and proceed to gnaw and suck up the insides of the host. In some regions are considered pests because adult females of many species sucks blood from humans and other animals transmiting a filarial worm in humans called Mansonella ozzardi.
