Orius insidiosus, common name the insidious flower bug, is a species of minute pirate bug, a predatory insect in the order Hemiptera (the true bugs). They are considered beneficial, as they feed on small pest arthropods and their eggs. They are mass-reared for use in the biological control of thrips.
Orius insidiosus adults are approximately 3 mm in length. This oval-shaped insect is black with white patches on the wings. Nymphs of this species are teardrop-shaped and wingless. They range from yellow-orange to brown in colour.
This species is common throughout the United States, and extends into Canada, Mexico, Central and South America. It also occurs in Cuba, Puerto Rico, and other islands of the West Indies. The female lays her eggs inside plant tissues, where they hatch into nymphs. Growth time from egg to mature adult takes at least 20 days. It is possible for several generations to occur during a single growing season.
Orius insidiosus prey on plant-eating (phytophagous) mites and their eggs, various insect eggs, and other soft-bodied arthropods such as thrips, spider mites, and small caterpillars. They also feed... Wikipedia →
