Pentatomoidea is a superfamily of true bugs in the order Hemiptera. It is a large and diverse group, with over 10,000 described species. The superfamily is divided into several families, including the Pentatomidae, Scutelleridae, and Tessaratomidae. Pentatomoidea are often referred to as shield bugs or stink bugs. They are typically found in a variety of habitats, including forests, grasslands, and agricultural areas. Some species of Pentatomoidea are considered pests, as they can damage crops and transmit diseases. Others are beneficial, serving as predators of other insects. The superfamily is found on every continent except Antarctica. Pentatomoidea are generally small to medium-sized insects, with a distinctive shield-like shape to their bodies. They have a hard exoskeleton and a pair of wings, which are often folded against their backs. The mouthparts of Pentatomoidea are adapted for piercing and sucking, allowing them to feed on plant sap and other fluids. The superfamily is thought to have originated during the Cretaceous period, around 100 million years ago. Since then, it has evolved into a diverse and widespread group of insects. Pentatomoidea are often studied by entomologists and other scientists, who are interested in their biology, ecology, and evolution. The superfamily is also of interest to farmers and gardeners, who seek to manage populations of Pentatomoidea that can damage crops. Overall, Pentatomoidea are an important and fascinating group of insects, with a wide range of characteristics and behaviors.
