Orb-weaving spiders spin the wheel-shaped webs often seen on dewy mornings in meadows and hedges, or on the walls and the eaves of buildings. This manual provides descriptions, illustrations, and taxonomic keys for the identification of the 94 species of these spiders represented in Canada and neighbouring regions.

Beetles are the largest and most studied order of insects, some of which are beneficial as biological control agents. Alphabetically lists all species and subspecies of beetles known to Canada and Alaska under their respective genus-group names. Includes a brief introduction for every family treated and an index to all supraspecific names.

New taxonomic, distribution and habitat data are presented for Canadian species in various families of Coleoptera. Distributional records are presented mostly from New Brunswick but also Quebec, Nova Scotia and Prince Edward Island. For New Brunswick, 320 new provincial records, 6 new records for Canada, and 22 new records of adventive species are provided. For Quebec, 1 new provincial record is provided; for Nova Scotia, 11 new provincial records are provided; and for Prince Edward Island, 2 new provincial records are provided. Maps of all new distribution records and significant new biological information are provided for all species. This volume on Maritime provinces beetle biodiversity contributes new and important baseline data, and significantly updates the known Coleoptera faunas of New Brunswick, Quebec, Nova Scotia, Prince Edward Island, and Canada.

"Beetles are incredibly diverse, with over 23,000 named species in the United States alone. They take on all hues, shapes, and sizes, from the iridescent green of the Western Cedar Borer to the striking red of the Rose Curculio. They can also be found in a wide range of habitats, from cold mountain streams to scorching deserts. Similar to its eastern counterpart, Beetles of Eastern North America, this book is a comprehensive guide to the beetles of the US and Canada that can be found west of the Continental Divide. It covers over 1,400 species across 130 different families. The book begins with a general introduction to beetles, with sections on morphology, behavior and natural history, and conservation, as well as information on how to find and photograph beetles. After the introduction, there is an illustrated key to common beetle families. The family descriptions include information on natural history, collection, identification, common genera and species, and similar families"--

This monograph includes all species in the families Anthribidae, Apionidae, Attelabidae, Brentidae, Ithyceridae, Nemonychidae, Platypodidae, and Rhynchitidae that occur or may occur in Canada and Alaska. The work includes a key to all the families of Curculionoidea in North America, as well as keys to all genera and species of the families included. Each genus is described. Species entries include a list of synonyms, a description, data on distribution, information on host plants and on other aspects of biology, and diagnostic features. Distribution maps and illustrations of taxonomic characters for a number of species are included, as well as habitus illustrations of representative species.

ÿThis volume includes fourteen research articles on Canadian Coleoptera, mainly on the families Staphylinidae, Leiodidae, Histeridae, Nitidulidae, Cucujidae, Phalacridae, Silvanidae, Laemophloeidae, Tetratomidae, several aquatic groups, and others. An introductory editorial traces the history of scientific research and indicates areas of future inquiry. The papers address various questions with respect to the distribution, dispersal, zoogeographical status, phenology, and bionomics of Canadian Coleoptera, the role of saproxylic beetles in forest ecosystems, and invasive species in native habitats. The answers to these questions have important economic and environmental consequences. The book is addressed to coleopterists, ecologists, biogeographers, and conservationists.
