Quick answer
Mosquitoes are small flying insects whose females bite animals and people to drink blood, which they need to produce eggs. They are considered one of the most dangerous animals to humans because some species spread diseases such as malaria, dengue, and Zika. Adult mosquitoes typically live only a few weeks.

Biology
Mosquito (Culicidae) is classified as Insect with conservation status Least Concern. Typical weight about 0.0000025 kg; lifespan around Adults a few weeks.
Ecology
Diet: Nectar; females also drink blood. Habitat: Worldwide near standing water. Movement and social systems reflect those pressures.
People and this species
Learn before you travel or keep related pets. Wild individuals are not toys; captive care needs species-specific husbandry.

Why mosquitoes bite
Only female mosquitoes bite, and they do so to get the protein in blood needed to develop their eggs. They locate hosts by sensing exhaled carbon dioxide, body heat, and skin chemicals. Both males and females actually feed on nectar and plant juices for everyday energy.
A dangerous disease carrier
Mosquitoes are often called the deadliest animals to humans because certain species transmit diseases as they feed. Malaria, dengue, yellow fever, Zika, and West Nile virus are all spread by mosquitoes, causing hundreds of thousands of deaths worldwide each year, mostly from malaria.
Life cycle and water
Mosquitoes lay their eggs in or near standing water, where the larvae and pupae develop before emerging as flying adults. Because they breed in even small pools, removing standing water around homes is one of the most effective ways to reduce their numbers.
Habitat and control
Mosquitoes are found almost everywhere people live, from tropical regions to temperate zones, and are most active in warm, humid conditions. Bed nets, insect repellents, draining standing water, and controlling larvae are key tools for limiting bites and the diseases they can carry.
Research notes
Figures for mosquitos (Culicidae) come from field studies, museum records, and conservation assessments that do not always agree on exact averages. Prefer ranges over single-point claims, and check whether a source describes wild, captive, or mixed populations.
Practical takeaways
If you encounter mosquitos in the wild, prioritise distance and local guidance. If you care for related domestic or captive animals, match diet and housing to species needs rather than generic pet advice. Share accurate status information (Least Concern) when discussing conservation.
