Insects of the Los Angeles Basin


Book Description

"Southern California is home not only to the country's second largest metropolitan center but to an estimated 3,000 to 4,000 different kinds of insects. Insects of the Los Angeles Basin provides an introduction to more than 400 of the most conspicuous or curious of these invertebrate animals and to about 70 spiders, mites and ticks, and related forms. With color photographs or drawings of all but a few species, the text describes the size and most striking physical characteristics of adults and immature stages and gives information on locomotion and behavior, offensive and defensive maneuvers, mating rituals, food preferences, nests and traps, and noises and scents. The specific habitat and general geographic range of each insect are included, as are lore and superstition regarding some notorious species." "The author, Dr. Charles L. Hogue, has answered the questions that he was most often asked in his position as Curator of Entomology at the Natural History Museum of Los Angeles County. The result is a highly readable text with an emphasis on the effects that insects have on the people who encounter them."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.
