Bionomics
The larvae of Coquillettidia attach to aquatic plants to obtain oxygen from air cells for respiration. A variety of plants are used, particularly grasses. Larvae detach and re-attach to host plants quite readily. The females of several species readily attack humans. Both nocturnal and diurnal biters are known.

Medical Importance
Some species of Coquillettidia are notorious pests of humans and domestic animals in Africa, Europe, and North America. Coquillettidia perturbans is a vector of Eastern equine encephalitis virus in North America.
