were collected seven times between 13 May and 21 June 1977. 
Results 
More male S. ocreata were captured than females (* 2 = 109.87, 1 df 
P<0.001), probably because this time of year was the breeding season 
for S. ocreata, and male lycosids are more motile than females (Vlijm 
and Richter 1966; Hallander 1967). Unequal numbers of males, 
females, and total (males + females) spiders were found across all 
three habitats (woods, ecotone, field) due to the relatively low 
number of spiders found in the field (Table 1). The number of males 
and total number of spiders did not differ between the woods and 
ecotone; the greatest number of females were found in the woods 
(Table 1).

Discussion 
Our data indicates that the distribution of S. ocreata was not 
restricted to the ecotone, as there was no difference between the 
number of spiders found in the woods and ecotone. Fewer spiders, 
however, were found in the field as compared to the other areas, 
probably chie to the lack of cover and to temperature/mositure 
extremes in this habitat. Cady (in prep.) worked with a dense 
population of S. ocreata that was found deep within a woodland site 
not far (< 50m) from Aspey’s (1976) study site. The spiders in the
