Not all mosquitoes suck blood. Female mosquitoes suck blood, while male mosquitoes don't. Female mosquitoes need blood to ovulate and reproduce. Female mosquitoes can suck blood three or four times a night, and each time they can suck out more blood than their own weight. Female mosquitoes secrete saliva to stop them from sucking blood.

This saliva is the reason why people and animals feel itchy after being bitten. The inhaled blood is transported to the midgut and stomach, and the stomach expands accordingly, which stimulates the brain to secrete hormones to the ovary and orders the ovary to begin to develop. In addition, the blood contains a large amount of protein, which is enough for the development and maturation of ovaries.

The life history of mosquitoes includes four parts: eggs, larvae, pupae and adults. Generally, eggs are 65,438+0-2 days, larvae are 5-7 days and pupae are 2-3 days. Adults emerge to feed on blood for 3-7 days, and the whole generation takes about 1-2 weeks.

The life span of mosquitoes is related to their species. Some species overwinter with eggs, some species overwinter with larvae, and some species overwinter with adults, so the lifespan of adults is naturally different.

Generally speaking, they can live for 1-4 weeks, and the long ones can live for several months, if the environment is suitable. Of course, we must rule out being photographed or
