Diagram of a social Anelosimus nest and the relationship between the prey capture area per spider and colony size. (A) Diagram of an Anelosimus eximius nest showing the basal basket-shaped section used primarily for habitation and the superior webbing used primarily to intercept and capture prey. The relationship between colony size and prey capture web area per spider (log₁₀ area per spider = 2.6201645 − 0.3546797 × log₁₀ number of spiders) shown in B is based on the superior webbing. Data are log transformed to satisfy normal distribution requirements of linear regression. Dotted lines indicate 95% confidence intervals.
