    Predatory Stink Bug - (Podisus placidus)


    Picture of Predatory Stink Bug
    Staff Writer (6/15/2017): 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.

    BUGFINDER: What Kind of Bug is This...
    BUGFINDER allows for a quick search of the Insect Identification database by selecting primary color, secondary color, number of legs and the territory / state in question. If only one color is present on your insect, select it again as its SECONDARY color. Remember that the more details you can offer, the better your chances of finding a match. As a rule of thumb, six legs are typical for most insects whereas spiders generally have eight legs.
