Rhyparochromus is a genus of insects belonging to the family Rhyparochromidae. These insects are commonly known as dirt-colored bugs or ground bugs due to their brown or grayish coloration, which helps them blend in with their surroundings. They are typically found in leaf litter, soil, or under rocks, where they feed on decaying organic matter. Rhyparochromus insects are small in size, measuring around 5-10 mm in length, and have a flattened body shape.
