Abstract

The mating behavior of the nursery web spider Pisaurina mira is described for the first time. These spiders mate while suspended from draglines as in Oxyopes heterophthalmus (Latr.) and Peucetia viridans (Hentz). The unique feature of the mating in P. mira, however, is the male's use of a veil of silk to wrap the female's legs I and II into a flexed position prior to copulation while her legs III and IV are held in a flexed position by the male's embrace. Mating is accomplished in a version of position II with body axes in a right angle as the female is cradled by the male's legs. The use of silk to "tie" the female is reported elsewhere only in Xysticus.
