| Abstract | Various aspects of the ecology of Lycosa carolinensis Walckenaer have been investigated in a Lower Sonoran Desert community, including surface activities, seasonal activities, and burrow construction . The average home range is 1 .1 m 2 and parts of the home range boundaries are proposed to be limite d by changes in topographical relief . Adults and immatures are inactive from November through February . Immatures reach thei r highest percentage during the months of March and October . The peak percentage of females an d males occur in June and July, respectively . Females have two peaks of egg sac carrying in late July and late August and can possibly have two broods of spiderlings per year. It is thought that females do no t reproduce until the third summer and possibly live one year or more. Males also mature in the third summer, but die the year they reproduce . The burrows occupied by L. carolinensis serve as a retreat from heat, desiccation, and som e predators. The burrows are randomly distributed with respect to each other but uniformly distribute d with respect to shrubs . Most of the burrows have turrets (87%), which probably function as an "early warning system . " In the laboratory, 72% of third, fourth, and fifth instar spiderlings construc t burrows which they later abandon, giving rise to the possibility that the spider can possess at least tw o burrows during a lifetime . |
