Pupae do not feed. This stage lasts only for two or three days. Both larvae and pupae are subject to heavy predation. Typically, the 100-400 eggs laid by a female only result in a few adults developing successfully. The adult stage appears in as little as 7-10 days in some mosquitoes.
Adult behaviors vary depending upon the species.
Some breed and live near water, which may be fresh or brackish. Other species may fly considerable distances from a breeding site to seek food sources. Some species are only active at dusk, while others seek blood meals during daylight hours. Only the females seek blood, which they need as a protein source to produce eggs. Males as well as females feed on flower nectar or plant juices for energy.
