Predatory Stink Bug offspring have all the flash and color of youth, but all that changes with maturity.
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 eating 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 closer 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.
