Commentary

Avatar of commenter Thank you for your report! Yes, that looks like Winter cutworm, although there are other cutworm species that look similar -- but management options are the same for most of them. In a vegetable garden, hand-picking and chickens are a good but time-consuming option. Here is a post from the OSU Extension service with some management advice:
