Dragonflies eat mosquitos. I happen to like dragonflies. The are one of the non-annoying insects I actually like to have in my (non) backyard.

When I was young, people were encouraged to build homes for Purple Martins, because it was believed that these birds ate a substantial quantity of mosquitos. Later it was discovered that they actually prefer to eat dragonflies. Oops!

In the UK we don't have human-biting mosquitos, yet we still have plenty of dragonflies.

We have plenty of human biting mosquitos in the UK, I'm quite allergic to some of them.
