Cutworm

Cutworms chew through plant stems at the base or even underneath the soil. Some species will climb plants as well and destroy foliage. In most cases, entire plants will be destroyed; they do a lot of damage in no time at all. Try patrolling your garden in dusk and evening hours, when cutworms will begin to feed. They are also partial to cloudy days. Keep a close eye on tomato and bell pepper crops.
