We tested whether laboratory groups of Coptotermes formosanus Shiraki forage randomly when they are given 4 equivalent wood blocks, and whether group size affects variance of feeding on equivalent blocks. In all cases, foraging was not random, but, rather, the termites concentrated on a few preferred blocks. Group size did not affect this pattern of non-randomness. These data are useful for designing choice tests, and recommended sample sizes for a simulated experiment are given.
