Through the project we plan to compare the number and diversity of dragonfly larvae collected this year to previous years.. The presence of several different species present which can indicate that the ecosystem is becoming more stable over time and can support a greater diversity of organisms that occupy these niches.. We also plan to determine if there is an increase in natural control organisms (such as carnivorous insects) which may reduce mosquitoes and other disease vectors. Dragonfly larvae which hunt small insects, mosquito larvae and small crustaceans and as adults prey on nuisance insect species are beneficial to the Peconic River ecosystem. They may help keep disease carrying organisms in check and improve the overall quality for humans to enjoy the river with fewer insect bites
