Beetles (Coleoptera) are a large and varied group of insects. There are two YNU interest groups involved, one looking after the group as a whole, and a second specialising in a single family of rove beetles, the Aleocharinae.

Bob Marsh has written the following sections of an Atlas of Yorkshire Coleoptera.

Some sections are in the final stages of publication and will be available once they are ready. The documents are available to download by clicking the links below.

Individual files range from 2MB to 10MB in size so may take some time to open/download.
