Cladocera Interest Group

The Cladocera Interest Group is an informal alliance of naturalists with an interest in the orders of micro – crustacean which are often conveniently referred to as Cladocera or Water Fleas. We have a wide variety of members from amateur microscopists and naturalists to professional entomologists and researchers, with all categories in between. Membership is free and open to all. Our Aims The basic aim of the group is to provide a means of communication between members, to share hints, tips and methods for the identification of water fleas, to encourage recording to species level and research on life history and behaviour. We formed in Britain in the hope that eventually a better picture of the distribution of these fascinating creatures across the British Isles may be built up such that we begin to see which species are common and which are rare.
