Natural England Commissioned Report NECR188 A review of the Hemiptera of Great Britain: The Aquatic and Semi-aquatic Bugs Dipsocoromorpha, Gerromorpha, Leptopodomorpha & Nepomorpha Species Status No.24 First published 20 November 2015 www.gov.uk/natural -england Foreword Natural England commission a range of reports from external contractors to provide evidence and advice to assist us in delivering our duties. The views in this report are those of the authors and do not necessarily represent those of Natural England. Background Making good decisions to conserve species should primarily be based upon an objective process of determining the degree of threat to the survival of a species. The recognised international approach to undertaking this is by assigning the species to one of the IUCN threat categories. This report was commissioned to update the national status of aquatic and semi-aquatic bugs using IUCN methodology for assessing threat. It covers all species of aquatic and semi-aquatic bugs (Heteroptera) in Great Britain, identifying those that are rare and/or under threat as well as non-threatened and non-native species. Reviews for other invertebrate groups will follow. Natural England Project Manager - Jon Webb,
