Top 10 Commonly Reported Butterflies and Moths of Connecticut

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.
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.
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.
Orange Sulphur Colias eurytheme	Quite variable. Upperside of male yellow with orange overlay, yellow veins, wide black border, and dark black cell spot. Female yellow or white with irregular black border surrounding light spots. Underside hindwing spot silver with 2 concentric dark rings, and a spot above it.
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.
Peck's Skipper Polites peckius	Upperside of male is brown with reddish-orange patches; forewing has a sinuous stigma. Female is darker with no stigma. Underside of the hindwing of both sexes has a patch of large yellow spots in the center surrounded by dark brown.
Little Wood-Satyr Megisto cymela	Light brown. Forewing has 2 yellow-rimmed black eyespots both above and below. Hindwing has 2 eyespots on upper side; but may have smaller spots below.
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.
American Copper Lycaena phlaeas	Upper surface of forewing shiny, fiery orange-red with black spots; hindwing gray with orange-red outer margin. Underside gray; hindwing with submarginal row of orange-red zigzags.
Great Spangled Fritillary Speyeria cybele	Large. Upperside of male tan to orange with black scales on forewing veins; female tawny, darker than male. Underside of hindwing with wide pale submarginal band and large silver spots.
