	Xerces Blue - Wikipedia, the free encyclopedia
		The Xerces butterfly is believed to be the first American butterfly species to become extinct as a result of loss of habitat caused by urban development.
		The Palos Verdes Blue (Glaucopsyche lygdamus palosverdesensis) which is considered a Los Angeles cousin of the Xerces, is being reared in labs.
		Xerces is also a group of XML software packages named after this butterfly.

		The Xerces Blue butterfly (Glaucopsyche xerces) is perhaps the most famous of the extinct United States butterflies.
		The Xerces Blue, in essence, was a species which consisted of only one population, although great variation was present in the individuals comprising the population.
		Xerces was a small butterfly, the upper wing surfaces iridescent blue-violet in the male, brown in the female.

		Perhaps the most famous extinct insect is the Xerces Blue (Glaucopsyche xerces) (pictured at right), for which the conservation organization the Xerces Society was named.
		But Herman was right, the Xerces blue was last seen flying over the dunes at the Presidio in El Presidio near San Fransisco in 1943 it was flying among the bell heads of the purple lupine, looking for nectar or looking for a site to lay eggs.
		The Xerces Blue's relatives still live not far from the site and there has recently been suggestion that they might be introduced in an attempt to bring back a species of Xerces to the area (Pyle 2000).

		The Xerces blue butterfly (Glaucopsyche xerces), was the first butterfly in North America known to become extinct as a result of human interference.
		The Xerces blue butterfly (see left), Antioch katydid, Tobias' caddisfly, Roberts's alloperlan stonefly, Colorado burrowing mayfly, Rocky Mountain grasshopper all were driven extinct by humans.

		Blues are tasty treats for predators and must rely on maneuverability to elude capture.
		The introduction of the invasive Argentine ant, Iridomyrmex humilis, worsened the plight of the Xerces Blue.

		The Xerces Blue is one of the only extinct insects relatively well known of its own accord.
		The males of the Xerces Blue, as their name suggests were small blue butterflies with white spots on the undersides of their wings.
		The stories of the Xerces Blue and the katydid Neduba extincta are instructive, they tell us something about the why these species went extinct and what they looked like, but they still don't give us a great sense of what disappeared when those species exited the universe.

		Local die outs of the Deerweed probably brought about occasional Xerces Blue population extinctions, but these were no doubt balanced by the butterfly's colonization of new areas.
		Urbanization eliminated most Xerces Blue populations during the 1930's, with the remaining vacant lot colonies surrounded by inhospitable city habitat.
		The Xerces Blue survived for awhile in this state, finally disappearing in 1942.

		The Xerces Blue butterfly is the first butterfly in North America known to have become extinct due to human disturbance.
		At about the time of the earliest declines in the Xerces Blue's populations a new species of ant had been introduced from South America, the Argentine ant (Iridomyrmex humilis) which has displaced numerous native ant species, particularly in urban and suburban areas.
		Though only the Xerces Blue has received widespread attention, the growth of San Francisco has undoubtedly brought about the decline or extinction of many undocumented insect populations, subspecies, and species.

		Living testament to nature's ingenuity, lepidopterans (literally translated to mean "shingle winged insects") are far more than pretty objects to be encased in lacquer, or decorative creatures to be pinned inside a specimen case.
		Several reside on the United States' endangered species list, and although the xerces is one of many that have been lost to the world forever due to habitat destruction, pollution, or intrusion by exotic species, for many, there is still some semblance of hope.
		More and more, these fragile creatures are being appreciated not only for beauty's sake, but for the delicate intricacies, interconnections, and balances in nature which they so vividly represent.

		The male Xerces Blue Butterfly was a brilliant blue-violet and the female was a soft brown.
		Now extinct, but always very rare, the Xerces Blue Butterfly was last seen in 1941 and was found only in the San Francisco Bay Area.
		After human encroachment and the clearing of the land for building homes, the extinction of the Xerces Blue Butterfly is blamed on the loss of suitable foliage where the females would have normally laid their eggs.

		The Xerces Blue butterfly (Glaucopsyche xerces) once lived in coastal sand dunes near San Francisco, California.
		A related butterfly, the Karner Blue (Lycaeides melissa samuelis), is one of eighteen butterfly species or subspecies on the U.S. Endangered Species list.
		Like the Karner Blue, it has very specific food plant needs: its caterpillars eat only Birdsfoot Violets, which tend to disappear when their habitat is degraded.

		Wild Lupine’s habitat ranges far beyond the narrow conditions necessary for the survival of the Karner Blue, but this butterfly cannot survive without a heavy snow pack to protect its larvae during the winter.
		The Xerces Blue butterfly, which laid its eggs on Lupine and Deer Weed, required a habitat found only in the coastal dunes of the San Francisco area.
		In 1943 an expanding military facility claimed the land on which the last remaining colony of Xerces Blue thrived.

		He found himself enthralled particularly by the Karner blue butterfly; he became engrossed in the butterfly, in its wellbeing and in the notion that it was quickly diminishing and in danger of ceasing to exist.
		In “Nabokov’s Blue Snowflake,” Robert notes briefly writer and lepidopterist Vladimir Nabokov’s contributions to the study of the Karner blue butterfly.
		For three weeks, the Karner blue caterpillar feeds on the leaves of the wild lupine, protected by both their color and roughly a dozen species of ant who act as body guards for the caterpillars while they eat.
