Keys for the identification of British Helophoridae

The members of this family occurring in Britain all belong to genus Helophorus and most occur in water. We have twenty species on the British list. The key below should allow the identification of the British species. Further details on the British species can be obtained from Keys to adults of the water beetles of Britain and Ireland (Part 2), Foster, Bilton & Friday (2014) available from the Field Studies Council.
