Yup, damselflies eat mosquitoes, bless their
little hearts. This is a good page about them.

Nobody here has been bitten by a mosquito all year.
We have big dragonflies around, tons of damselflies,
froggies and, of course, the fish.
All pots without any critters in them are treated with
mosquito bits.
