The Cerambycidae, or longhorned beetles, are one of the larger insect families, with some 20,000 described species (and thousands more undescribed) worldwide, from all continents except Antarctica. The large size and variety of coloration and sculpture of longhorned beetles make them a relatively easy group of insects to identify, especially considering the number of species (some 1,100 species estimated in North America excluding Mexico); this guide attempts to exploit this. This guide includes over 600 color images, covering 342 of the 344 species and subspecies of longhorned beetles that have been definitively recorded in northeastern North America, along with diagnostic features to enable recognition of all these species, as well as data on distribution, phenology, and larval feeding habits.
