Conservation interest in moths, by far the predominant components of Lepidoptera, lags far behind that for butterflies, for which conservation practice provides many well-established lessons for extension to their near relatives. The needs of moths are at least as great, but their greater richness and variety, and far poorer documentation of diversity and biology over much of the world contribute to this lack of attention. Australiäs rich moth fauna, largely endemic and of global interest, illustrates many of the problems of developing wider interest and support for moth conservation. Numerous species (perhaps half the total fauna) are undescribed, and many are ecological specialists in restricted and vulnerable environments over small parts of the continent. Establishing their conservation status and needs whilst accepting that foundation knowledge is highly incomplete and much species-focused conservation is impracticable provides complex problems in setting priorities, based largely on wider diversity and effective advocacy. Most Australian vegetation systems, from grassland to forest and from sea-level to alpine zones, have been eroded in extent and quality since European settlement, resulting in massive habitat changes for native insects and to leave fragmented (and commonly degraded) remnants in which moths and others may persist. Recent surveys continue to increase recorded moth richness, reveal local faunal peculiarities, and indicate how assemblage changes may mirror wider environmental changes. This book is an overview of advances in documenting and interpreting moth diversity and ecology, to show how information from better-studied moth faunas can help in planning conservation of Australiäs moths through measures such as understanding the moths themselves by increased surveys and study, the factors influencing their diversity and wellbeing, and how such threats may be countered through increased coordinated conservation interest, commitment and management.

A series of original papers and reviews dealing with the peculiarities of island insects and their conservation in many parts of the world. Contributions to this special issue of Journal of Insect Conservation range from biogeographical analyses and ecological features of island insects and their evolution to the variety of concerns for their wellbeing, and practical conservation through a variety of, sometimes novel, approaches. They provide a valuable and up-to-date resource for entomologists and conservation practitioners.

This broad overview of Australian forest insect conservation draws on studies from many places to demonstrate the diversity and vulnerability of forest insects and how their conservation may be pursued through combinations of increased understanding, forest protection and silvicultural management in both natural and plantation forests.

The book introduces basic entomology, emphasising perspectives on insect diversity important in conservation assessment and setting priorities for management, as a foundation for managers and others without entomological training or background.

A survey of the development and practice of butterfly conservation in south east Australia, tracing evolution of the science through a series of cases from focus on single subspecies through increasing levels of ecological complexity to critical biotopes and communities.

Examples from many parts of the world and ecological regimes demonstrate the variety of mutualisms between insect taxa, and between insects and plants, in particular, and their significance in planning and undertaking insect conservation - of both individual species and the wider contexts on which they depend.

Includes chapters on assessing changes among assemblages and in individual species, the variety of general threats (notably habitat changes and impacts of alien species) and more particularly urban threats.

This overview of the roles of alien species in insect conservation brings together information, evidence and examples from many parts of the world to illustrate their impacts (often severe, but in many cases poorly understood and unpredictable) as one of the primary drivers of species declines, ecological changes and biotic homogenisation.

A global synthesis of the impacts of wildfires and controlled burning on insects, bringing together much hitherto scattered information to provide a guide to improved conservation management practice.

This survey of one the longest insect conservation campaigns in Australia deals with one of the most iconic endemic papilionid butterflies, the Richmond birdwing. It shows different factors that can influence community interest and practical outcomes.
