Mosquito
Mosquitoes of the genus "Toxorhynchites" never drink blood. This genus includes the largest extant mosquitoes, the larvae of which prey on the larvae of other mosquitoes. These mosquito eaters have been used in the past as mosquito control agents, with varying success.
De Havilland Mosquito
There are approximately 30 non-flying Mosquitos around the world with four airworthy examples, two in the United States, one in Canada and one in New Zealand. The largest collection of Mosquitos is at the de Havilland Aircraft Heritage Centre in the United Kingdom, which owns three aircraft, including the first prototype, "W4050", the only initial prototype of a Second World War British aircraft design still in existence in the 21st century.
