Lifecycle of a Mosquito
Female mosquitoes generally require a blood meal before eggs can be laid. Depending on her species, the mosquito adult may feed on birds, pets, wildlife or you. Because of her slender mouth-parts, the female mosquito’s bite is often painless. Mosquitoes are drawn to a combination of our body scents and to the carbon dioxide we exhale.
Shortly after the bite, the spot may become itchy and form a flattened “wheal” or bump, like you see here. A few mosquitoes, unfortunately, introduce disease-causing viruses into the blood during feeding. Mosquito-borne diseases include several kinds of encephalitis and West Nile virus.
