A Comparison of Populations of Wolf Spiders (Araneae, Lycosidae) on Two Different 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, from December 1981 through November 1982. It was found that the faunas were different in species composition, even though they were within a few meters of one another. Light-colored species, such as Lycosa ceratiola and Lycosa osceola, were more abundant on or restricted to the sandy 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 lycosids were collected.
