Mt Charleston Blue Butterfly

The Mt. Charleston blue butterfly is a distinctive subspecies of the wider ranging Shasta blue butterfly (Plebejus shasta), which is a member of the Lycaenidae family. The wingspan of the Mt. Charleston blue butterfly ranges from ¾ to one inch. The upper side of males is dark to dull iridescent blue and females are brown with a blue overlay. Their underside is gray, with a pattern of black spots, brown blotches and pale wing veins, which give it a mottled appearance.

 

The Mt. Charleston blue butterfly only occurs at high elevations (6,600 – 8,600 feet above sea level) primarily on the east side of the Spring Mountains in the Spring Mountains National Recreation Area of the Humboldt-Toiyabe National Forest, approximately 25 miles west of Las Vegas in Clark County, Nevada. The butterfly requires open habitats that support its larval host plant, Torrey’s milkvetch (Astragalus calycosus var. calycosus), which grows at elevations from 5,000 to 10,800 feet above sea level in the Spring Mountains.

    It is very sad that self serving politicians play into the hands of reactionaries who know nothing of the complexities of life on this planet. Their only interest is how to make a quick easy buck. It may seem daft to protect a species if one looks at the protection as a cost to the taxpayer. Nothing could be further from the truth. The preservation of even the seemingly insignificant species has implications far beyond that particular animal or plant. The only reason the human species has survived on this planet for the last few hundred thousand years is because of a diversity of habitats and species to exploit for food and sustenance. There is also the largely unknown realm of plants and animal species from bees to beetles and fish to birds,sharks and whales all critical to the survival of someone. If each and every person simply understood that diversity of species is our own survival and not some soft fantasy to be shunned and ridiculed. We can slow down the progression of the largest mass extinction since the dinosaurs if we simply acknowledge the problem and face it head on instead of pretending it doesn't exist.
