Here we can see several individuals sharing the same cobweb. These spiders are social and in this genus several species are social. Unluckily the species is not known. Nevertheless, the social spiders of this genus are known to carry out team work to achieve what only one spider cannot. For example to subdue a big prey. As many individuals as needed will collaborate to perform the task and there is no hierarchy when starting to feed. This genus is also characterized by the creche system, in which the spiderlings feed from any female providing food, no matter who.
