P. placidus is a type of Predatory Stink Bug. They have sucking mouthparts that are used to siphon nutrition out of a food source. Members of this species suck on plant juices when very young, but graduate to caterpillars and sawfly larvae as adults.

The physical form of juvenile and adult are different. Young nymphs are round and mostly red, looking somewhat like small Lady Beetles. As they develop, bands of white lines form and they grow in size (see photo gallery). Adults are neither red, nor black, but a drab brown. This coloring is camouflage and allows them to get close to their insect prey undetected.

Adults hibernate over winter and emerge in the spring to seek mates. Females lay fertilized eggs under leaves or other objects where they hatch within a week in the right conditions. After several instars, P. placidus reaches maturity in a month.

A Note About Territorial Reach: Keep in mind that an insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above. Insects are driven by environmental factors, food supplies and mating patterns and do not nescessarily work within hard-and-fast territorial lines like we humans do.
