New Jersey Butterflies

American Lady

Vanessa virginiensis

Identification: Small—2.0" (much smaller than the similarly orange Monarch). Above: FW and HW orange and black with a few white spots in black FW apex. FW usually has a small white spot in the outermost orange square nearly halfway along outer margin. Black marks on inner FW near body do not form a connected arc (as in Painted Lady). Below: HW dark olive with intricate pale cobweb pattern, a conspicuous pale band across the midwing, and 2 large, blue-centered eyespots near margin. Painted Lady has 4 smaller eyespots, but it's often easier to see the pale band on American, which is lacking in Painted. FW with pinkish-orange area just above edge of FW.

NJ Status and Distribution: Resident. Usually fairly common and widespread. Migratory. Abundance varies from year to year depending on degree to which immigrants supplement residents.

Comments: Occasionally a very faded individual is seen in April that probably spent the winter in some protected crevice or woodpile.
