The larvae mainly feed on Artemisia vulgaris, but may also feed on maize. Before boring the stalks of their host plant, early instar larvae graze on young plant tissues that are mostly apical.[3] They are typically found in corn fields, gardens, and commercial crop plantations and they are usually active from April to October.[2] They are primarily found in Japan, although they can be found in other regions of Asia and Europe as well.[4]
