Mosquitoes
Culicidae (mainly Culex, Aedes, Anopheles spp. in the U.S.) · Mosquitoes, Ticks & Chiggers
Mosquitoes are small, long-legged flies. Only the females bite, because most need a blood meal before they can lay eggs. They breed in standing water, even small amounts like plant saucers, clogged gutters or old tires, so a yard can produce its own supply. Most bites only itch, but some mosquitoes in the U.S. can spread diseases such as West Nile virus.
Look for: A slender fly with long, thin legs and a long, needle-like beak that lands on skin to feed. The wings are covered in tiny scales.
