What Do Mosquitoes Look Like?
Of more than 3,000 documented mosquito species, the United States is host to 150. The appearance, habitat and habits of mosquitoes vary by species.
All mosquito species have one pair of scaled wings with a pair of halteres. Mosquitoes have slender bodies with long legs. While their size varies by species, most mosquitoes are smaller than 15 millimeters in length and weigh less than 2.5 milligrams. Although mosquitoes appear fragile, they are extremely resilient insects that prey on a variety of animals.
The most common urban mosquito, the northern house mosquito, is brown in color with white markings on its legs and proboscis. The Asian tiger mosquito is slightly smaller than other mosquito species. White scales along its thorax, black and white scales along its abdomen and black and white striated legs, characterize it. The Anopheles quadrimaculatus is brown in color and can be distinguished from other mosquitoes by three long projections located upon its head. This mosquito is responsible for the spread of malaria within the United States. The most dangerous of this species bears white patches on the wing-veins.
