Papillons et libellules du Québec
Agrion à tache jaune
Chromagrion conditum| Aurora damsel

This black and blue damselfly is distinguished by the bright yellow marks on the lower sides of thorax. Its wings are partly spread when perched, which is a distinct characteristic from other damselflies in this family. The female's pattern is similar to the male's, but light brown to gray compared to blue in the male.
