A COMPARISON OF POPULATIONS OF WOLF SPIDERS (ARANEAE, LYCOSIDAE) ON 2DIFFERENT SUBSTRATES IN SOUTHERN FLORIDA

Wolf spiders were sampled from sandy and grassy substrates every month for one year at Archbold Biological Station, Lake Placid, Florida, fr om December 1981 through November 1982. It was found that the faunas w ere different in species composition, even though they were within a f ew meters of one another. Light-colored species, such as Lycosa cerati ola and Lycosa osceola, were more abundant on or restricted to the san dy surface, while darker colored species, such as Lycosa miami, Lycosa annexa, Lycosa abdita and Schizocosa crassipes were more abundant on or restricted to, the grassy substrate. A total of twelve species of l ycosids were collected.
