The narrow blue line on the thorax of the Double-striped Bluet are a helpful feature for identifying this summertime damselfly.
Damselflies are slender, flying insects that are commonly found near water. The Double-striped Bluet is no exception. The two noticeably thinner pale lines on the thorax sit near the 'shoulder' area. Males have blue lines among black stripes; females have pale blue, white, or tan lines among the black stripes. The last two segments of the long abdomen on the male is completely blue, but the female's may be tan or only partly blue.
The common resting position has the wings flattened together near the body. Water is necessary for egg-laying, so adults are often seen near streams, pond, lakes, and slow rivers. They move quickly, but they are harmless to people. Their diet of pest insects like mosquitoes and flies means they are a beneficial insect to humans as well as the ecosystem.

Grayed-out selections indicate that the subject in question has not been reported in that particular territory.
