This is because these areas lack fish that prey on insects giving the dainty damselfly a safe habitat to live and reproduce in.
[8] The dainty damselfly was formerly recorded as a breeding species in Britain and had thought to have become locally extinct after the North Sea flood of 1953.
[9][10] There was a large viable population in East Anglia, but after the flood many seasons passed by without any sightings of the dainty damselfly leading to the conclusion that they had been extirpated.
[1] There are many factors contributing to the geographic movement of C. scitulum some of these include changing temperatures, land disruption and decreasing water levels.
The number one cause of dispersal in dainty damselflies is rising temperatures as they tract their optimal thermal niche to new locations.
There has been studies completed on the dainty damselfly showing that genetic diversity can influence the success of colonization and can decrease resistance to stress and disease.
[12] The dainty damselflies are being exposed to pesticides more frequently due to their dispersal and need to cross agricultural land to reach new habitats.
[8] The genetic diversity and structure of dainty damselflies are shaped by both historical rapid range expansions and contemporary processes causing dispersal like environmental factors (climate change).
