Yes, for very good reason the Damselfly is our friend. What is the reason?

From Wild-Facts.com: "imagine you and your sweetheart are enjoying a nice romantic picnic when all of a sudden you are bombarded by mosquitoes and blackflies. Of course this isn’t very pleasant but Damselflies are doing their best to ensure that your picnic isn’t taken hostage by natures annoying insects. Okay, so maybe they are just hungy and enjoy eating those pesky little bugs, but the end result is still the same….less mosquitoes and blackflies to bother us."
