rise of immatures in June 1978. Leaves were counted arbitrarily as 
the stand was circled. Collections were made from 0 to 2 m above 
ground level ,on both the outside edge and within the stand. All 
spiders with prey were preserved separately and identifications of 
the prey obtained from various specialists. Carapace widths were 
measured using a dissecting microscope equipped with an ocular 
micrometer for 20 specimens per sample, if available. The number 
of instars was calculated by using a method of simple regression of 
carapace widths developed by Hagstrum (1971). It was assumed that 
salticids exhibit a similar mean relationship between logarithms of 
carapace width and stadium (log y=0.0871x — 0.2692 where 
x=stadium and y=carapace width) as Lycosids, Loxoscelids, 
Clubionids, Oxyopids, and Ctenizids. Egg masses collected on the 
magnolia trees were allowed to hatch and the time spent in the first
