The difference between a noctuid and a cutworm at two o'clock in the wheat field.

Hello! Noctuidae larvae are 1.4- 1.8 cm long, yellow gray or dark brown. The obvious feature is that some nodules have inverted triangles with dark brown stripes, and there are two brown back lines on the back of the abdomen, which disappear to the chest.

The last larva of the cutworm larva is 37 ~ 50 mm in length and 3 ~ 3.5 mm in head width. The body color is dark, ranging from yellow brown to dark brown. There are dark brown longitudinal bands on the back of the body, and the epidermis is rough and covered with small particles of different sizes.
