American Lady Caterpillar

Vanessa virginiensis


Larvae: Full grown larvae are approximately 1.4 inches in length (Minno et al. 2005). The body color is variable. Some larvae are primarily yellow with thin black transverse lines on the anterior and posterior margins of the segments and a narrow transverse black band in the middle of each segment. In some larvae, the median black band is much wider so that the larvae appear to be black with narrow yellow lines. There is a transverse row of large branched spines (scoli) with orange or red bases on each body segment, Abdominal segments two through eight typically have a conspicuous white spot on each side and there is usually a creamy white lateral line that runs most of the length of the body.


Caterpillar Hosts: Plants in the sunflower family everlasting (Gnaphalium obtusifolium), pearly everlasting (Anaphalis margaritacea), plantain-leaved pussy toes (Antennaria plantaginifolia), wormwood (Artemisia), ironweed (Vernonia), and burdock (Arctium).
