Top 10 Commonly Reported Butterflies and Moths of Wyoming

Mormon Fritillary Speyeria mormonia	Small, with large rounded antennal clubs. Upperside tawny to orange-brown; male with no black scales on veins. Underside of hindwing orange-brown; base sometimes slightly darker or greenish. Spots are usually silvered.
Purplish Copper Lycaena helloides	Upperside of male brown with purple iridescence; female more orange. Hindwing of both sexes with broad orange band at margin.
Rocky Mountain Parnassian Parnassius smintheus	Antenna has alternate black and white rings. Upperside of forewing of females and most males with 2 red or yellow spots beyond the cell. In some males these spots are black.
Milbert's Tortoiseshell Aglais milberti	Forewing tip squared-off. Upperside is black with a wide orange submarginal band which grades to yellow at the inner edge of band. Narrow black marginal border on both wings; the hindwing border may contain some blue spots.
Clouded Sulphur Colias philodice	Upper surface of male wings bright, clear yellow with solid black edging; lower side of forewing with some dark submarginal spots; hindwing with silver cell spot rimmed with orange-pink, usually doubled. Female has 2 forms: yellow form with uneven black edging enclosing yellow spots, and a white form which is greenish-white rather than yellow. Spring and fall forms are smaller and less conspicuously marked.
Common Checkered-Skipper Burnsius communis	Upperside of male is blue-gray; female is black. Both sexes have large white spots which form median bands across both wings. Fringes of male checkered but black checks often reach only halfway to edge of fringe. Male has a costal fold enclosing scent scales on the upperside of the forewing. Underside is dull white with dark gray or olive bands. Spots of the hindwing marginal row are very small; spots of the submarginal row are larger. This species is separated from the white checkered skipper with confidence only by dissection and examination of the male genitalia.
Callippe Fritillary Speyeria callippe	Upperside tawny to bright red-brown with dark, evenly-spaced markings. Underside has triangular silver submarginal spots with narrow brown edging; other spots large and usually silvered.
Painted Lady Vanessa cardui	Upperside is orange-brown with darker wing bases; forewing with black apex patch and white bar on leading edge; hindwing submarginal row of 5 small black spots sometimes has blue scales. Underside has a black, brown, and gray pattern with 4 small submarginal eyespots.
Hoary Comma Polygonia gracilis	Upperside is dark red-orange, borders darker; hindwing with yellow submarginal spots. Underside is gray-brown; outer half much lighter, frosted white or silver-gray. Silver spot at center of hindwing is fishhook-shaped.
Boisduval's Blue Plebejus icarioides	Upperside of male lilac-blue with dark borders. Female may be brown, or blue with wide dark borders. Below, black or white postmedian spots are larger on forewing than on hindwing.
