They become active in spring after host plants emerge, mate and lay eggs on the underside of leaves. Nymphs hatch from eggs in about 2 weeks. Development from egg to adult occurs in 45 to 60 days, and up to three generations may occur annually. Injured leaves appear grayish and may wilt and die. Populations increase during the season and large numbers of nymphs may occur on the fruit in the fall.
Adults are more solitary and tend to occur around the base of the plant near the ground.
When crushed, a disagreeable odor is released by this insect. Hypselonotus is another genus of coreids that is frequently encountered. Eggs can be found by examining the underside of leaves. Injured leaves appear grayish and may wilt and die. Nymphs can be collected by tapping them off the plant into a jar or other suitable container.
