    The female hangs upside down in a tangled sheet web and gyrates very rapidly if disturbed. She carries the bundle of eggs in her chelicerae, loosely surrounded by silk threads, until they hatch. It is thought to be of American origin, imported first into France and then into Britain on wine bottles.
