Western Pygmy-Blue Butterfly
Description: Tiny. Upperside copper brown with dull blue at the bases of both wings. Underside of hindwing is copper brown with white at the base, fringe mostly white. 3 small black spots near base; row of black spots at outer margin. Diet: Adults eat flower nectar; caterpillars eat on tumbleweed. Breeding and Young: Blue green eggs hatch into light green caterpillars. Males patrol over the host plants all day to find receptive females. Females lay eggs all over the host, but mostly on the upperside of leaves. Interesting and Unique: This butterfly is the smallest butterfly in the Western United States. The species occurs in large numbers, but is easily overlooked. The coming of man and the introduction of weeds has increased its population. |
