Mosquito pupa and larva. Light microscope footage of a front view of a mosquito pupa (family Culicidae) at the surface of water. On the right is a mosquito larva with its siphon (breathing tube). 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. After one to two weeks the larvae 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.
