Mosquito larvae and pupae

Videonummer 11945299
Mosquito pupae and larvae. Light micrograph of two mosquito pupae (family Culicidae) at the surface of water, with mosquito larva in the foreground. Mosquito larvae are aquatic and breathe through spiracles located on their abdomen, or through a siphon (breathing tube) on the end of the abdomen as seen here. They feed on algae and other detritus suspended in the water for one to two weeks, and then pupate. Each pupa has a fused head and thorax (cephalothorax) and segmented abdomen. After a few days, depending on the water temperature, the pupa rises to the surface of the water, the cephalothorax splits and the adult emerges.
