Ecological Role

Herbivore; larval feeding on diverse plant . Potential pest of cultivated plants including celery (Apium graveolens), cabbage (Brassica oleracea), sweet potato (Ipomoea batatas), alfalfa (Medicago sativa), cowpea (Vigna sinensis), and rose (Rosa odorata).

Human Relevance

Potential agricultural pest due to larval feeding on multiple crop . Not known to be of major economic significance.
