I love dragonflies and damselflies. You can tell the difference when they rest on a plant. The dragonfly will keep his wings open, while the damsel fly closes hers against her back. I also think the damsel fly looks more delicate! Azure Damselfly
Dragonfly and Damselfly Identification Dragonfly fact! How do you tell the difference between dragonflies and damselflies? The damselfly is generally smaller and they hold their wings pressed together at rest, whereas the dragonfly holds their wings straight out.
Another fact is that adult dragonflies will devour just about anything they can catch. Dragonflies usually eat mosquitoes, bees, gnats, butterflies, termites, and other bugs. When they are in the nymph stage, they eat small fish, tadpoles, mosquito larvae, worms, and aquatic insects.
