Appearance
The adult of "P. punctulatus" is 11-13 mm long and has a mostly black body with a yellow spot at the apex of the scutellum. There are six legs which are black and cream in colour. The head as well as the humeral angles of the pronotum are pointed.Behavior
The life cycle of this species has been studied in Union County, Illinois. Adults overwinter in leaf litter near their host plants. They become active in June and reproduce. Eggs are usually laid singly. These eggs hatch into nymphs which go through five instars. A laboratory experiment, rearing "P. punctulatus" on "Tradescantia subaspera" under constant temperature and light, found that on average egg incubation takes 9.04 days while the five nymphal instars take 5.06, 7.15, 7.56, 9.32, and 15.93 days.Food
"Proxys punctulatus" is omnivorous, feeding on both plant juices and on insect larvae. It has been found on blackberry, spiderwort, cotton, soybean and citrus plants. Feeding results in disfigured leaves and discolored areas on stems, but this damage is usually insignificant since the bugs never reach high populations.References:
