Ocypus olens, commonly known as the Devil's Coach Horse beetle, is a large, black, predatory beetle found across Europe. It inhabits gardens, forests, and fields, and is known for its defensive posture, raising its abdomen like a scorpion. It plays a vital role in controlling pest populations.

Ocypus olens, commonly known as the Devil's coach horse beetle, is native to Europe and North Africa. It is particularly widespread in Western Europe, including countries such as the United Kingdom, Ireland, France, Spain, and Portugal. The species has also been introduced to other regions, including North America, where it has established populations.

Ocypus olens typically inhabits temperate regions with moderate climates. It is commonly found in environments that are moist and rich in organic matter, such as woodlands, gardens, hedgerows, and grasslands. The species prefers habitats that offer ample cover and places to retreat during the day, as it is primarily nocturnal.

The Devil's coach horse beetle plays a role as a predator within its ecosystem. It is an opportunistic carnivore, feeding on a variety of invertebrates, including slugs, snails, and other insects. This predatory behavior helps control the population of these organisms, contributing to the balance of the ecological community. The beetle is well-adapted to foraging in leaf litter and under stones, where it can hunt effectively.
