The black cutworm does not generally overwinter in Illinois, except possibly for pupae or mature larvae in southern areas. This is the first stage that is capable of cutting corn stems.

The name cutworm refers to the habit of the larvae, of cutting down and partly eating garden and crop plants, especially seedlings. The larvae feed above ground for about the first quarter of their lives, or until they are approximately half an inch long.

Black cutworm larvae vary in color from light gray to black and are about 1 ½ inches long when fully grown. Tillage and herbicide application just before planting do not always help since the eggs would have already been laid. Numerous convex skin granules give the larvae an overall shiny and "greasy" appearance. Pests of crops in warmer climates and their control.

Biological activity of essential oil of Sage plant leaves was evaluated against 2nd instar larvae of A. ipsilon. Early larval instars fed aboveground until . Factors that favor black cutworm outbreaks are late tillage and planting, reduced tillage, infestations or weeds prior to planting, low spots in a field, fields next to permanent vegetation, and excess crop residue (such as in no-till fields). Degree-days can be used to predict larval development and when the first cutting of plants may begin.

Moreover, because relatively few major cutworm outbreaks have occurred in Illinois in the past 10 years, a grower also may find an economic advantage to the wait-and-see system, which involves field scouting rather than a costly pre-plant rescue treatments are the amount of surface moisture and the movement of the cutworms.
