 This can make the insect more susceptible to toxins such as pesticides which in turn also affects the dainty damselflies' ability to continue their dispersal through slow movement, reduced population growth and flight ability.The dainty damselflies are being exposed to pesticides more frequently due to their dispersal and need to cross agricultural land to reach new habitats.It's not just dispersal due to climate change that causes the genetic changes in the dainty damselfly though, it can also happen due to natural range expansion as well.
