Abstract: | During the social period, molting behavior of the young spider, Amaurobius ferox, is highly synchronized within the clutch. Result of the experimental study suggests that social facilitation among group members increased the synchronization. The duration of the molting period of grouped spiderlings was significantly shorter than that of individually isolated spiderlings. Involving the particular maternal strategy in food supply, this phenomenon might have adaptive values in the maintenance of mutual tolerance among the siblings by decreasing the interindividual difference in development and in the avoidance of cannibalism on molting individuals. This probably will also serve to make the peaceful collective behaviors of the spiderlings in matriphagy and cooperative prey capture during their social period. |
