The Summer Azure is a beautiful light blue butterfly that is enjoyable to watch as it flutters up and down among the plants. It is one of the smallest butterflies in North America. The upperside of the male is powdery blue, often with ill-defined white patches on the hindwing. The females have white scaling on both forewings and hindwings. The underside of the hindwing is pale gray or white with small black dots and a dark zigzag line. The Hindwing fringe is solid, with no checkering.
