Alphabetical List of Critters - Cutworms

Cutworms, in spite of the name, are not ‘worms’ at all, biologically speaking, but are actually a kind of hairless caterpillar that turn into moths upon completion of their development. As larvae, they generally hide during the day, and come out at night to feed, safe from most predators and from the heat of the sun.  They often start eating the first part of an acceptable host plant that they encounter, which is often the stem, resulting in the plant (especially a seedling) being ‘cut’ straight through; hence the name cutworm. Cutworms are categorized as surface, climbing, army or subterranean. Because of their many similarities, it is often difficult to tell one species of cutworm from another. However, there is variation in life cycles. In Maine, many cutworms have only one generation per year, although some can produce two generations. Corn, peppers, tomatoes and beans seem to be their favorite food, but they will attack many kinds of plants.
