Beetles of the Outer Hebrides

The Coleoptera are the largest group of insects in the world although in Britain the Hymenoptera and Diptera are more diverse. It is difficult to make comparisons but Waterston (1981) estimated that the beetle fauna of the Outer Hebrides was about half that of mainland Scotland at a similar latitude. The lack of suitable habitats, particularly woodland, and the island effect are probably responsible for the absence of many species that are found on the mainland. However, in common with many of the invertebrate groups, beetles are relatively unrecorded and there is still a great deal to be discovered about their diversity and distribution throughout the archipelago.
