Multiple dark eyespots on the underside of the wing and the curvature of its brown lines are key to recoginzing this particular Pearly-eye.
Like a bright pearl in an oyster, the black eyespots of a Pearly-eye butterfly have a small white pupil in the center. The Northern Pearly-eye has yellow rings around its eyespots. Four of them are on the forewing; six more are on the hindwing, the first of which is larger and more forward, out of line with the others. Brown lines, like a watermark, cross the wings closer to the body, and even highlight some veins. The Creole Pearly-eye looks similar to this species, but has five eyespots on the forewing and a brown line that reaches out toward the eyespots. The Northern Pearly-eye's brown line does not. The Northern also has black tips on its antennae. The top side of the wings are muted brown and while the eyespots are visible on that side, too, they lack the pearly pupil.
The caterpillars of this species feed on grasses. Though adults do not drink flower nectar, they do take liquids from tree sap, rotting animals, fungi, and even moist feces. Look for them nears forests and in grasslands.

Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
Butterfly and Moth Anatomy
Antennae: Butterflies and Moths have a pair of antennae on the head used as sensors.
Head: The head is home to the insect's eyes, antennae, and proboscis.
Thorax: Home to the three pairs of legs as well as vital internal organs.
Abdomen: Contains vital internal organs such as the heart(s) and reproduction facilities.
Forewing: The upper, forward wing pair used for flying.
Hindwing: The lower, rearward wing pair used for flying.
NOTE: Butterflies and Moths are part of the Lepidopteran order as they share many similarities.
