The third in a trilogy of global overviews of conservation ofdiverse and ecologically important insect groups. The first twowere Beetles in Conservation (2010) and Hymenoptera andConservation (2012). Each has different priorities andemphases that collectively summarise much of the progress andpurpose of invertebrate conservation.
Much of the foundation of insect conservation has been built onconcerns for Lepidoptera, particularly butterflies as the mostpopular and best studied of all insect groups. The long-acceptedworth of butterflies for conservation has led to elucidation ofmuch of the current rationale of insect species conservation, andto definition and management of their critical resources, withattention to the intensively documented British fauna'leading the world' in this endeavour.
In Lepidoptera and Conservation, various themes aretreated through relevant examples and case histories, andsufficient background given to enable non-specialist access.Intended for not only entomologists but conservation managers andnaturalists due to its readable approach to the subject.
