It is a ‘good’ insect called ground beetles (Family Carabidae), which are important predators in the field. Ground beetles are known for preying on other insect pests and feeding on weed seeds. So, they provide natural control of both insect pests and weeds in field. Who won’t be scared of those huge pinching mandibles! This is a Pasimachus sp. (identified by A. Knudson, NDSU Plant Diagnostic Laboratory). There are about 2,000 species of ground beetles in North America.
