Abstract
Damage to corn by 3rd-instar larvae of Hydraecia micacea (Esper) began in late May or the first week of June and continued until pupation in mid-July, with peak damage occurring the second and third weeks of June. On average, larvae damaged four corn plants in completing their development. Only 0.69% of damaged plants survived in the field. The first symptoms of attack always occurred within 24 h and are described and discussed. H. micacea larvae moved from grassy field edges into corn over a 2-month period beginning in late May. Damage was most severe adjacent to these grassy edges, and decreased logarithmically with distance from them.
