![]() ![]() Black cutworms progress through a series of metamorphoses, beginning with an egg and progressing to an larval stage, a pupal stage, and an adult stage. The life cycle of a person is an example of this. During the day, they are active, but at night, they hide. Their wings are covered in two white stripes, and their antennae are long and white. The cutworms are one inch long and have a black body with a yellow head and neck. Aerobic holes are commonly found on turfgrass, and the larval stage is closely clipped around them. The larvae will feed at night, either in the thatch layer beneath the soil or through a burrow under the surface of the soil during the day. They also consume leaves and crowns, which may result in the removal of plants from the soil’s surface. What Time Of Year Are Cutworms Most Active?īetween the middle of March and the beginning of October, the cutworms and armyworms emerge. The cutworm is tolerant of cold temperatures, and larval feeding activity is ongoing throughout the fall and winter. Noctua pronuba is the name given to a larval stage of the large yellow underwing moth (Noctua pronuba). Feeding is more difficult in new seedings than it is in existing stands. In Michigan, feed was reported for sugar beets, Swiss chard, squash, and other diets. In addition to beets, cabbage, carrots, grape, grasses, lettuce, potatoes, strawberries, and tomatoes, the Noctua pronuba caterpillar has been linked to a variety of other foods. Extensive defoliation of hay is one of the first confirmed reports. ![]() This insect, known as the yellow underwing in the United States, has been linked to a significant amount of economic damage due to extensive defoliation of hay. In the fall of 2007, thousands of Noctua pronuba caterpillars were discovered in Michigan. ![]() This means that you can reduce the population of these pests simply by allowing winter temperatures to do their work. Cutworms are very sensitive to cold temperatures and will die when exposed to prolonged freezing weather. One of the most effective methods is to simply wait for winter weather to arrive. Fortunately, cutworms are relatively easy to control. The larvae of these moth species feast on the leaves of young plants, often causing serious damage. In many regions, cutworms are a common garden pest. ![]()
