Butterfly
(Plebejus anna) The Anna's Blue butterfly is a common species in the Cascade Range.  The butterfly is univoltine, meaning it has one brood per year.  In the Fall the butterfly lays its eggs in lupine to overwinter.  The caterpillar eats the Spring away on lupines, Torrey peas, and trefoil.  In completes metamorphosis in the summer to start the cycle again.  The adults feed on the nectar of the host plants of the larvae.  These butterflies are usually found above 3000 feet in elevation.

The Common Blue is the most widespread blue butterfly in Britain and Ireland and is found in a variety of grassy habitats.\nThe brightly coloured males are conspicuous but females are more secretive. The colour of the upperwings of females varies from almost completely brown in southern England to predominantly blue in western Ireland and Scotland, but the colour is variable within local populations with some striking examples. Unlike Adonis and Chalkhill Blues, the dark veins do not extend into white fringes of wing margin
