• Cockroaches are generic insects with limited adaptations, and they may be the most basic Neopteran insects still alive.
• Most species are reddish-brown to dark brown in color, with a tiny head and broad, flattened bodies.
• They feature long, flexible antennae, huge compound eyes, and two ocelli.
• On the bottom of the skull, the mouthparts comprise generic chewing mandibles, salivary glands, and different touch and taste sensors.
• A three-segmented thorax and a ten-segmented abdomen comprise the human body.
• A robust exoskeleton made of calcium carbonate covers the outside of the body, protecting the internal organs and providing muscular attachment.
• Water repellent wax is applied to its exterior exoskeleton.
• The second and third thoracic segments have wings connected to them.
• The tegmina, or first pair of wings, are robust and protective, and they serve as a shield over the membranous hind wings, which are utilized for flying.
• Each of the four wings has several cross-veins and branching longitudinal veins.
