Silvery Blue butterfly is easily missed, as it has a wing span of only 2.2 to 3.2 cm. In males, the tops of the wings are silver-blue with black edges. Females are duller, or sometimes even brown. The underside of both have a dirty gray colour with a row of black spots edged in white close to the outer edges.
In Algonquin Highlands these butterflies seldom fly more than 50 cm off the ground, staying close to feed on Lupine blossoms, Wild Pea, Vetch or others. They are in flight from May to late June and can be seen in, rocky moist woodlands, road edges open meadows and brushy fields.
Eggs are laid singly on flower buds and young leaves of the host plants. The caterpillar is light green with white spots, deep green stripes edged in yellow, and a black head. As the larva produce a sugar-like liquid called Honeydew, they can often be seen surround by ants and other insects.
Adult Silvery Blue drink nectar from flowers including Asteraceae.
