typically faced downward. Individuals rested more often in an 
upright position on the upper surface of the leaf (illumination — 
approx. 400 lux) than they did in an inverted position beneath the 
leaf (illumination = approx. 130 lux). 
We considered each spider’s behavior within the 2-hr periods of 
observation and noted that each remained within the “herbaceous 
stratum” during the entire 2 hr in 5.3 (range = 4-7) of the ten 
periods. Each spider remained on the ground throughout the 2-hr 
period in only 1 .6 ( range = 0-3 ) of the ten periods. The spider 
moved from the ground to the foliage or vice versa in the remaining 
3.1 (range = 2-4) of the ten periods. 
Some observations made on several female L. punctulata in the 
artificial habitat indicated that these spiders also tended to spend 
their time resting on the foliage. However, we did not quantify 
this part of our study. 
After completing the 1 0-day survey of stratum selection by L. 
rabida, we observed and filmed prey-wrapping by these spiders on 
the artificial foliage. The behavior resembled that performed on the 
floors of the housing containers, as we described above. Wrapping
