Confidence votes 4. Almost all insects have four wings, but the mosquito is one of only a few types of insects that actually only has two wings. Mosquitoes, Flies, Gnats and all the members of the hymenoptera or bee family only have two wings. However, there are two funny little knobs behind the first set of wings that are probably evolutionary remainders of what used to be a second set of wings.
To give you a little insight, the dragonfly that is many times the size of a mosquito or a housefly needs to flap its wings a mere 30 times a minute when compared to a mosquitoâs 600 times a minute and the houseflyâs 1000 flaps a minute requirement to keep them flying and in peak maneuverability.ardly! Adult Dragonflies are born rulers of their domain and they prove it to just about every insect that thinks it can pull a fast one on this killing machine. The adult dragonfly uses the basket formed by its legs to catch insects while flying.
