Figure 1. Mean weights of 19 light-fed and 15 heavy-fed Araneus 
diadematus with standard errors (vertical lines). Figures are for both 
sets of spiderlings combined. Sharp increases in weight in the light-fed 
group are due to the animals being weighed before and after feeding. 
Note the increasing difference in weight between the light-fed and heavy- 
fed group.
