Both sexes responded equally to food restriction

<p>The collected juveniles were randomly assigned into two groups (Nstarving = 161, Ncontrol = 159), the control group was supplied with abundant food across the entire experiment process, and the experiment group was provided with only half amount of required food resource for the entire development process.In order to investigate the effects of food restriction on the development duration, adult body length and weight of spiders and the differences between female and male spiders, we measured the body length of each spider every five days since the experiment started until they reached adulthood, then their body weight, sex and the development duration were recorded.In order to explore the behavioral responses, concerning daily time allocation and hunting, of spiders between different food conditions, sexes and growth stages, we randomly selected some spiders from "Experiment 1" and carried out the following trails. Detailed number of spiders from each sex, each growth stage and each food condition are summarized in supplementary materials.</p>
