A dragonfly is a flying insect belonging to the infraorder Anisoptera below the order Odonata. About 3,000 extant species of dragonflies are known.

The larvae develop within 38 to 65 days, [17] which allows this migrant dragonfly to reproduce in temporary waters or even in swimming pools. [18] However, the larvae seem to be very sensitive to temperature. [19] The life expectancy is not known and because of their high mobility it is almost impossible to determine.
About eight to 10 different species account for the lakefront dragonfly swarms, according to Jackson. However, if you spot a dragonfly, it'll most likely be a common green darner, which is among ...

Libellula quadrimaculata, known in Europe as the four-spotted chaser and in North America as the four-spotted skimmer, is a dragonfly of the family Libellulidae found widely throughout Europe, Asia, and North America.
