Top 10 Commonly Reported Butterflies and Moths of Illinois

Monarch Danaus plexippus	Upperside of male is bright orange with wide black borders and black veins; hindwing has a patch of scent scales. Upperside of female is orange-brown with wide black borders and blurred black veins. Both sexes have white spots on borders and apex. The Viceroy butterfly (Limenitis archippus) is a Mullerian mimic; it has similar coloration and is also distasteful.
Eastern Tiger Swallowtail Papilio glaucus	Male is yellow with dark tiger stripes. Female has 2 forms: one yellow like the male and the other black with shadows of dark stripes. Hindwing of both female forms has a row of striking blue chevrons and an iridescent blue wash over parts of the interior hindwing. The upperside hindwing has a prominent orange marginal spot that is generally larger than the row of pale marginal spots. On the underside of forewing of spring individuals the row of marginal spots may be merged into a continuous band, thus appearing similar to the Canadian Tiger Swallowtail.
Red Admiral Vanessa atalanta	Upperside is black with white spots near the apex; forewing with red median band, hindwing with red marginal band. The winter form is smaller and duller, summer form larger and brighter with an interrupted forewing band.
Pearl Crescent Phyciodes tharos	Quite variable. Males usually have black antennal knobs. Upperside is orange with black borders; postmedian and submarginal areas are crossed by fine black marks. Underside of hindwing has a dark marginal patch containing a light-colored crescent. Spring and fall broods (form marcia) have a gray mottled hindwing below.
Black Swallowtail Papilio polyxenes	Upper surface of wings mostly black; on inner edge of hindwing is a black spot centered in larger orange spot. Male has yellow band near edge of wings; female has row of yellow spots. Female hindwing with iridescent blue band. In the Southwest, yellow forms predominate in the subspecies P. coloro.
Eastern Tailed-Blue Cupido comyntas	One narrow tail on hindwing. Upperside of male iridescent blue; summer females uniformly brown, spring females smaller with much blue at the wing bases. Underside of hindwing pale gray with black bar at end of cell, distinct black spots, and three large orange spots at outer margin near tail.
Silver-spotted Skipper Epargyreus clarus	Wings are brown-black; hindwing is lobed. Forewing has transparent gold spots; underside of hindwing has a metallic silver band.
Cabbage White Pieris rapae	Upperside of wings white; forewing with black tip. Two submarginal black spots in female, one in male. Underside of hindwing and forewing apex evenly yellow-green or gray-green. Spring and fall short-day form is smaller, less yellow, with reduced black areas.
Common Buckeye Junonia coenia	Upperside is brown. Forewing with 2 orange cell bars and 2 eyespots; part of white subapical band appears in the largest, lower eyespot. Hindwing has 2 eyespots; upper one is largest and contains a magenta crescent. Underside of hindwing is brown or tan in the wet season (summer) form and rose-red in the dry season (fall) form.
Question Mark Polygonia interrogationis	Forewing hooked; upperside is red-orange with black spots. Upperside hindwing of summer form is mostly black with a short tail; that of winter form has much orange and a longer, violet-tipped tail. Underside is light brown; hindwing with pearly white question mark in center.
