Pearl Crescent (Phyciodes tharos)

Pearl Crescent (Phyciodes tharos)

Pearl Crescent is abundant in N.C. and often overlooked because it's so common and often dull.

Pearls are highly variable. Similar species to look out for include the Silvery Checkerspot (mountains and piedmont), the recently described Mimic Crescent (mountains), which is sometimes considered to be a race of Northern Crescent, and Phaon Crescent (only along the immediate coast).

Note the pearly white crescent on the trailing edge of the hindwing, which gives the species its name. The rare Tawny Crescent of the mountains lacks the pearl mark and the dark area surrounding it. The Mimic Crescent male has orange on the underside of the antennal clubs -- not that this Pearl has orange on the top side of the antennal clubs only.
