***Eleodes osculans***, the **wooly darkling beetle** or **woolly ground beetle**, is a common insect in coastal southern and central [California](/source/California) in wooded areas or [chaparral](/source/Chaparral), and in [Baja California](/source/Baja_California).[2][1] As a stink beetle of genus *[Eleodes](/source/Eleodes)*, its easily observed defensive posture is to raise its hind end and secrete an unpleasant odor. *E. osculans* has a length of 12–16 mm and is the only known [darkling beetle](/source/Darkling_beetle) species with reddish-brown hair covering most of its black [exoskeleton](/source/Exoskeleton).[2][3] It is similar to *[Eleodes nigropilosa](/source/Eleodes_nigropilosa)* and *[Eleodes littoralis](/source/Eleodes_littoralis)*, which have darker hair.[3]
