Greater Yellow Underwing (Noctua Pronuba)
Last evening, about dusk, I glanced at my corn, and saw this climbing up a stalk.
It shares some of the characteristics of a black cutworm, and had some differences. When disturbed, it rolls up into a ball, it emerges from the soil in the evening, and has a soft body. There are also some differences; it does not have symmetrical dots on it’s back, in no literature could I find a description of a cutworm having the dots on its back, and it is “blacker” than the pictures of cutworms that I could find.

An Oregon State University Agricultural Extension Agency volunteer identified the moth larvae as a greater yellow underwing (Noctua Pronuba), just another fancy cutworm. There are several photos of the adult on the Internet, which will be left for you to discover.
They will damage a corn crop. Control is via BT or diatomaceous erath.
