Deraeocoris brevis
predatory plant bug
Deraeocoris brevis is a predatory plant bug in the family Miridae, native to western North America. Adults are small, glossy black insects 3–6 mm in length with red eyes, while nymphs are mottled pale grey with dark patches and a felted dorsal surface covered in grey hairs. Both life stages are predatory, feeding primarily on pear psyllids, aphids, spider mites, leafhoppers, and scale insects. The species is considered beneficial in apple and pear orchards of the Pacific Northwest, where it contributes to biological control of pest populations.
