One of the most intriguing phenomena known to science is the phenomenon of dragonflies migration. This is a phenomenon whereby certain species of dragonflies fly thousands of miles in search of the next patch of ground where they will lay their eggs. This phenomenon is best explained by thinking of it as the migration of birds. Except for the fact that dragonflies tend to be wingless, this is the way they take off in search of greener pastures.
The exact time frame for dragonflies to migrate is not known. They usually migrate within a year or two although it has been known to take as long as six months to travel a considerable distance. It’s generally accepted that the farther the dragonflies travel the greater the chances are that they will end up somewhere near the land bridges between continents. There, at the end of their journey they may start what is called “genetic winter” which can cause the death of all the dragonflies population.
When the weather turns cold and the nights grow longer and colder the dragonflies must seek shelter in the foliage of trees and bushes. But they cannot survive very long in these areas because the temperature is extremely cold. As the days become longer and the temperatures start to rise, the dragonflies are then forced to move into deeper, warmer regions of the forest.
