Table I
Recruitment and foraging distances for M. mandacaia trial. For comparison with van Nieuwstadt and Iraheta (), we give distances over which 75%, 95%, and 100% of total foraging activity occurred. Morphometric data show the average ± SD of head width (HW), interocular distance (ID), and intertegular distance (IT). Body size measurements give the mean ± 1 standard deviation of continuous, overlapping distributions.
