The lives of spiders are as varied as they are fascinating. There is also a remarkable diversity of species both worldwide (about 40,000) and within North America (about 3,500). Spiders are easy to find almost everywhere — all we have to do is go out (or sometimes in) and look for them. When searching for spiders, it helps to have a solid foundation of knowledge to increase your chances of finding interesting species and to enrich your experiences with the ones you do find. The beautifully illustrated resource Spiders is a terrific companion for spider-watchers, as it describes their evolution, anatomy, and behavior as well as the many ways spiders benefit ecosystems and humans. Familiar and unusual species are highlighted, and there is a handy section on what to do if you receive a venomous bite. Finally, there are notes on the various threats spiders face coupled with tips on how we can protect them. Laminated for durability, this lightweight, 12-panel folding pocket guide is the ideal companion for educators, learners, naturalists, and invertebrate enthusiasts who are curious about this overlooked but important group of eight-legged invertebrates.
