Two-spotted Stink Bug (likely)

Natural Habitat

Agricultural fields, gardens, and other areas where their prey (Colorado Potato Beetles and other insect larvae) are present. They are often found on host plants of their prey, such as potato, tomato, and eggplant.

Diet & Feeding

Predatory. Both nymphs and adults are beneficial predators, primarily feeding on the larvae and eggs of the Colorado Potato Beetle (Leptinotarsa decemlineata). They also prey on other soft-bodied insect larvae.

Behavior Patterns

Perillus bioculatus is an active predator. Adults are known to overwinter in sheltered locations and emerge in spring to lay eggs. Nymphs hatch and develop through several instars, all of which are predatory. They use their piercing-sucking mouthparts to paralyze and then consume their prey. They are most active during the day.

Risks & Benefits

Benefits: Considered highly beneficial in agriculture due to their effective predation on the Colorado Potato Beetle, a significant pest of potato crops. They help in natural pest control, reducing the need for chemical insecticides. Risks: No known direct risks to humans or significant negative impacts on the ecosystem.
