Western Pygmy Blue Habitat, Range, and Ecology

What’s in a name? In this case, the name fits rather perfectly. The Western Pygmy Blue is partly blue, diminutive, and lives primarily along the west coast of the United States.

It will occasionally reach as far north as Oregon as well as in smaller numbers in portions of Mexico and Venezuela.

For reasons that remain unclear, the insect prefers to inhabit areas of desert, wasteland, and salt marshes, though they will venture outward.

The caterpillars also feed on a variety of plant species while the adults feed exclusively on nectar.
