Acmon Blue

Icaricia acmon, the Acmon blue, is a North American butterfly. It ranges mainly in California and Oregon but can also be seen in southwestern Canada and in the Great Plains Region of the United States, with a total range of about 2,500,000 square km. Because of the breadth of its range, it occurs in several different habitats, such as grasslands, fields, shrub lands, forests, and deserts. [2] Amcon blue was discovered by Pierre Lorquin in 1850, while he visited California during the Gold Rush. It is believed that Amcon Blue was discovered in the San Francisco area. [3]

Wingspan is between the range of 17-30 mm. [4] The tops of the wings are blue with dark edges in males and brown in females. Its underside is white with black spots for both sexes and a red-orange band on the hindwing. [5] Caterpillars are yellow with white hairs and a green stripe down the back. [4] The Acmon is richly colored, more specifically the females with contrasting rows of red lunules (sometimes fused into a band). Meanwhile, the male's hindwing lunules tend to become pink and may disappear during autumn. [6]

Like many other lycaenid butterflies, it has a mutualistic relationship with ants, who protect Acmon blue larvae in exchange for honeydew that the larvae secrete.


Diet

Adults: Feed on nectar

Caterpillars: Feed on, leaves, flowers,deerweed, buckwheats, lupines, trefoils, fruits of wild buckwheat, legumes such as trefoils, [7] and milkvetches. [8] [4]


Risk of Extinction

Not much is known about the predators of this species, but the Acmon blue is at risk due to global warming and decreased/changing precipitation levels caused by human development. [9]

<span class="mw-page-title-main">Common blue</span> Species of butterfly

The common blue butterfly or European common blue is a butterfly in the family Lycaenidae and subfamily Polyommatinae. The butterfly is found throughout the Palearctic and has been introduced to North America. Butterflies in the Polyommatinae are collectively called blues, from the coloring of the wings. Common blue males usually have wings that are blue above with a black-brown border and a white fringe. The females are usually brown above with a blue dusting and orange spots.

<i>Anthocharis midea</i> Species of butterfly in the family Pieridae

Anthocharis midea, the falcate orangetip, is a North American butterfly that was described in 1809 by Jacob Hübner. It belongs to the family Pieridae, which is the white and sulphurs. These butterflies are mostly seen in the eastern United States, and in Texas and Oklahoma. They eat the nectar of violets and mustards. They tend to live in open, wet woods along waterways, in open swamps, and less often in dry woods and ridgetops. This species is a true springtime butterfly, being on the wing from April to May.

The great purple hairstreak, also called the great blue hairstreak, is a common gossamer-winged butterfly species in parts of the United States. It is actually a Neotropical species; its North American range only includes the warm-temperate and subtropical parts of that continent, and it ranges southwards almost to the Isthmus of Panama. The type specimen, however, was shipped to Europe from the Colony of Virginia, probably around the time of the United States Declaration of Independence.

<i>Eurytides marcellus</i> Species of butterfly

Eurytides marcellus, the zebra swallowtail, is a swallowtail butterfly native to the eastern United States and south-eastern Canada. It is the state butterfly of Tennessee. Its distinctive wing shape and long tails make it easy to identify, and its black-and-white-striped pattern is reminiscent of a zebra. The butterflies are closely associated with pawpaws, and are rarely found far from these trees. The green or black caterpillars feed on the leaves of various pawpaw species, while the adults feed on flower nectar and minerals from damp soil.

<i>Eriogonum fasciculatum</i> Species of flowering shrub

Eriogonum fasciculatum is a species of wild buckwheat known by the common names California buckwheat and flat-topped buckwheat. Characterized by small, white and pink flower clusters that give off a cottony effect, this species grows variably from a patchy mat to a wide shrub, with the flowers turning a rusty color after blooming. This plant is of great benefit across its various habitats, providing an important food resource for a diversity of insect and mammal species. It also provides numerous ecosystem services for humans, including erosion control, post-fire mitigation, increases in crop yields when planted in hedgerows, and high habitat restoration value.

<i>Lycaena heteronea</i> Species of butterfly

The blue copper, also known as Lycaena heteronea, is an American butterfly that belongs to the gossamer-winged family. The butterfly is named so because of the bright blue hue of the upper side of the males' wings. Females are brown on their upper side. Both sexes are white with black spots on the underside of the wings. Blue coppers are seen on the west coast of the United States and the southwest region of Canada, particularly British Columbia and Alberta. The males are often confused with Boisduval’s blue, another species of butterfly. Blue coppers prefer to live in areas where species of Eriogonum are found. Blue copper larvae sometimes form mutualistic associations with Formica francoeuri, an ant species.
