A colloquial name sometimes used for a dragonfly because of its habit of feeding on mosquitoes.

Dragonflies, also known as mosquito hawks, are excellent control agents. Dragonfly naiads consume mosquito larvae in the breeding waters, and adult dragonflies eat adult mosquitoes, particularly the day flying Asian Tiger Mosquitoes. Fogging for adult mosquitoes can backfire and increase long term populations if it removes dragonflies and other natural controls. Lizards are also useful predators which eat mosquitoes indoors.
