I do like dragonflies. They keep down the mosquito population. The adults catch adult mosquitoes and the larva or whatever they are called catch and devour the mosquito larva. They are rely vicious when in the water stage, it took me years to figure out what they were. If you put them in a glass and drop in a worm, they will attack and devour it ferociously.
