These spiders are harmless cousins of black widows within the cobweb spider family, theridiidae. They are distributed around the world, often residing in close proximity to humans. They are social spiders, sometimes living in large webbed colonies. Their commonality have made them useful research subjects for scientists interested in social arachnids.
