Pearl Crescent (Phyciodes tharos)

Common and widespread in NC, these butterflies can be found on the wing from Spring into Fall and often visit flower gardens. Males and females are distinguished by the shape of the tip of the abdomen (fine point in females; blunt in males).

Beware that identification can be challenging at times, and Pearl Crescents can be confused with Mimic Crescent (P. incognitus), Phaon Crescent (P. phaon), and Silvery Checkerspot (Chlosyne nycteis).

Where their ranges overlap in the NC mountains with Mimic Crescents, Pearls are generally smaller and the undersides of the antennal clubs on males are black (not red-orange). Note that the tips of the clubs may have varying degrees of orange, as this individual shows.
