The all-black body of the Devil's Coach Horse is just the one reason to think this a nefarious creature. Its elytra (wing covering) has no shine and appears dull in any kind of light. The abdominal segments are easily to distinguish. This member of the Rove Beetle family can inflict a painful stab from its massive jaws to an unsuspecting human hand.
The Devil's Coach Horse takes on an interesting look when disturbed or threatened, giving potential predators as well as unheeding humans fair warning. It will raise its abdomen forward, akin to a scorpion and its tail, and then open an internal gland that shoots out a yellowish foul-smelling fluid.
Devil's Coach Horses are not native to the United States and originated from Europe. Despite being exotic, they have established themselves in the Western and Southwestern regions of the United States. They normally prey on snails and slugs and can be found low altitudes and moist areas such as in parks and gardens where more regular watering may occur.
