The females take between 40 and 100 days, with an accompanying five to seven molts.

As these spiders live in constant presence of the human beings, in their habitat, they are not usually aggressive and will even not let a human hand approach their web.

Further disturbance may lead to the spider dropping down on a thread, and then running away from the web.
