Common Names in English:
Mountain Checkered, Mountain Checkered-Skipper
'The Hesperiidae are members
of the Superfamily
Hesperioidea. Worldwide in distribution, skippers are richest in the tropics. More than 3,500 species are described, with approximately 275 in North America, many of which are found only in Arizona and Texas. Most skippers are small to medium, usually orange, brown, black, white, or gray. A few have iridescent
colors. Skippers have large eyes, short antennae (often with hooked
clubs), stout bodies, and three pairs of walking legs
. Their flight is often rapid, making wing
movement appear blurred. Adults
of most species have long probicscises and feed
nectar, but some also take up nutrients
from bird droppings. Males have scent scales
found in modified forewing
patches. Males of most species locate mates by perching
and giant-skippers), though some patrol, especially in the open-winged skippers. Globular
are laid singly.
Pyrgines are primarily tropical American species of the Family Hesperiidae. There are approximately 80 North American species. Most genera are tropical, but the duskywings and checkered-skippers are mainly temperate and also occur in Eurasia . Adults of many species land with their wings open, although some perch with their wings closed or half open. They imbibe nectar from flowers, and males of many species take in moisture from moist sand or mud . Some adults also feed on bird droppings. Many tropical species rest underneath leaves when inactive . Females lay eggs singly. Most species lay eggs directly on host-plant leaves, while others lay on nearby plants or objects. Almost all species use broad-leafed plants as their caterpillar hosts, and caterpillars live in rolled-leaf or webbed-leaf shelters .
Species Pyrgus xanthus
Upperside is dark grayish brown with 2 broken , irregular rows of white spots across both wings . Underside is similar to upperside, but duller. White hindwing fringe is streaked with black to the edge of the fringe. Male does not have a costal fold. (ref. 104971)

Wing span : 3/4 - 1 inch (2 - 2.5 cm).
High mountain clearings from 8000 to 10,500 feet in elevation .
Males patrol but usually perch in gullies all day to watch for receptive females. Eggs are laid singly on leaves or flowers of the host plants . Caterpillars make a webbed shelter in which they rest and feed .
