Water beetles are among the most diverse freshwater macro-invertebrates: in still waters, around half the species detected in a typical pond-net sample will be beetles. This makes these insects important to any understanding of wetland biodiversity.

Yorkshire has a particularly rich fauna of aquatic Coleoptera. Amongst the groups covered by this atlas, 78% of the British species were recorded in the County in 2000-2016. This reflects the unique biogeography of our region, straddling the divide between the northern and western uplands and the eastern lowlands. Saltmarshes, ponds, fens, bogs, upland tarns, rivers and springs all support their own distinctive assemblages. Numerous species reach the northern or southern limit of their English distribution in Yorkshire, so this atlas will provide a baseline to help monitor future changes. Forty-eight Yorkshire water beetles are categorised as Nationally Scarce, 17 as Near Threatened and eight as Vulnerable.

This atlas is based on an intensive survey of Watsonian Yorkshire producing just over 62,000 records for the period 2000-2016. Records are mapped for each of the 210 species at a tetrad (2 x 2 km square) resolution, providing a fine-grained picture of regional distribution.

In addition to the species accounts, there is a brief history of water beetle recording in Yorkshire, a review of Quaternary subfossils, advice on survey methods, a summary of additional species recorded in the 19th and 20th centuries, and a chapter on wetland habitats.

Beetles ~ Contacts and Recorders


The YNU Recorder for all Coleoptera excluding Aleocharinae is Mr Bob Marsh,  11 Crusader Drive, Sprotborough, Doncaster DN5 7RX. Tel: 01302 788411 E-mail:

The Recorder for Aleocharinae (rove beetles) is Mr Mike Denton, 77 Hawthorn Terrace, Crosland Moor, Huddersfield, HD4 5RP.  Tel: 01484 646990 E-mail:


The beetle sub-section holds just under 230,000 records in a Recorder 6 database.  All of these records are passed on to national Coleoptera recording schemes, many of whom share the records via the NBN Gateway.  The records have also been passed to Doncaster Biological Records Centre and are in the process of being passed to North and East Yorkshire Ecological Data Centre.

Members of the YNU and its affiliated societies made a substantial contribution to Ladybirds (Coccinellidae) of Britain and Ireland, with Bob Marsh collating all the Yorkshire records.
