The dung beetle is a specific variety of scarab beetle, known for subsisting at least partially on faecal matter. The dung beetle (specifically Scarabaeus sacer) was worshipped by the ancient Egyptians, as Ronald Weasley noted when Hermione Granger stated the Egyptians worshipped cats. Giant dung beetles are a known magical related species to their smaller cousins, shown in Fantastic Beasts and Where to Find Them (film).
