Common species

Despite all the concern about disappearing species there are still many common ones. These often play a vital role in balancing ecosystems and it is important that we protect their habitats to ensure they remain abundant.

For example the devil's coach horse beetle, Ocypus olens, is a beneficial insect. Its diet ensures that organic matter is broken down and nutrients are returned to the food chain and the soil.

Find out about some of the common species studied by Museum scientists that play an important role in their ecosystems and maintaining our environments.
