Changing distributions of Cantharidae and Buprestidae within Great Britain (Coleoptera)

Changing distributions of Cantharidae and Buprestidae within Great Britain (Coleoptera) Data are presented on the distribution of selected species from two coleopteran families chosen to represent a random slice of the British fauna. The species have been chosen as exhibiting extremes of range changes, from declining species, through stable distributions, to expanding species. Examination of this small group of beetles already reveals significant changes, some of which may be related to global climate change. Predictions can be made about which others of these beetle families are likely to show detectable changes in range in the near future.
