Habitat:  The Silvery Blue can be found throughout all of Alberta and is very common in poplar forests and meadows.

Description:  The Silvery Blue is closer to grey than silver on the underside of its wings with blue on the inside.  Each wing was a distinctive row of black spots running across them.

Size:  25-30mm

Diet:  The caterpillars of the Silvery Blue consume the buds and flowers off legume plants

Fun Fact:  Due to the voracious appetites of the caterpillars, scientists believe some plants have evolved to bloom at specific temperatures so the caterpillars do not have a chance to eat all the flowers.
