Identification:

Echo azures are butterflies that, as their name suggests, are a chalky blue-gray in color. They are fairly small butterflies with wingspans usually between 2 to 3 inches wide. Besides the chalky blue-gray color of their wings, echo azures can also be recognized by their triangular brown spots.

Fast Facts:

  • Echo azure eggs are laid on the buds of plants which larvae, after emerging, will feed on.

  • Echo azure larvae are often tended to by ants, sometimes pupating in ant nests.

  • Adult echo azures will go through several generations between early spring and fall, after which  flight is possible. In higher elevations, the  period until flight is shorter.

  • Important host plants for echo azure caterpillars include wild lilacs, California buckeye, and blackberries. Adult echo azures will feed on the nectar of both caterpillar host plants as well as a variety of others.
