New Jersey Butterflies

Crossline Skipper

Polites origenes

Identification: Very small—FW ~0.6". Sexes similar below. Above: Male: Large, black, tapering stigma crosses center of FW rather than paralleling leading edge, and separates orange along leading edge of FW from dark brown remainder of wing (which includes 2 or 3 small yellow spots adjacent to the stigma). Female FW is overall dark brown, sometimes with a tawny leading edge, and includes 3 pale "bracelet" spots" toward wingtip and 2 or 3 conspicuous pale spots in center of wing. HW in both sexes may have a vague pale to orangey center. Below: Both wings dull brownish, HW with a band of pale postmedian spots that may be conspicuous, faint, or nearly absent. Similar skippers: Tawny-edged is smaller, usually shows more contrast below between dull brown HW and orange on leading edge of FW, and spotband, if present, is usually faint. Male's stigma is thick, not tapering, and there is a rectangular pale spot at end of stigma.

NJ Status and Distribution: Resident. Uncommon and local throughout.
