Adults have a wingspan of about 40 mm. This cutworm overwinters as eggs in soil or under trash. Eggs hatch in the spring and larvae feed beneath the soil surface on roots and stems at first, but also feed on the foliage. The most severe damage occurs from late March through early June.  When mature, larvae pupate in the soil.  Adults begin emerging in late June through early September.   Adults lay eggs in the fall. Eggs undergo embryonic development and form the overwintering stage. Select samping and action threshold to calculate damage levels.
