These stink bugs overwinter as adults in leaf litter and emerge in the spring when they will mate. After mating, females will begin depositing eggs on the underside of leaves on the plants where they hang out looking for food. A single female is capable of laying up to 500 eggs, depending upon how plentiful food is, as well as how nutritious her food choices were.
I find these stink bug frequently around out farm and can appreciate the beneficial service they are providing in controlling the harmful insects in our garden and our crop fields.
