Fuchs, T.W. and J.A. Harding. 1976. Seasonal abundance of arthropod predators in various habitats in the lower Rio Grande valley of Texas. Environmental Entomology, 5(2): 288-290.


Arthropod predators in various habitats were sampled weekly with a D-Vac® vacuum insect collector during 1973–75 in the Lower Rio Grande Valley of Texas. Data indicate that non-cultivated habitats support larger numbers of predators/unit area than do cultivated habitats. [b]Over 50% of all predators collected were spiders.

An excellent handbook for those interested in studying, collecting, keeping spiders, etc.

The fauna and color plate sections pertain to the more commonly encountered British spiders, but many of the covered families, genera, and even species, occur in North America as well.

The second half of the handbook is useful for anyone interested in spiders anywhere. Informative sections regarding collecting, captivity, photography, safety, and more, are included.
