Difference between Larva and Pupa of Mosquito

Life cycl of mosquito consists of four distinct stages: eggs, larvae, pupae and adults. Larvae are herbivorous. They feed on minute aquatic vegetation. They grow in size by moulting three times and in about two weeks they increase in size and change into the next stage called pupae. The pupa is a non feeding stage in which old organs disintegrate and new are formed to change into the young mosquito.
