Arabesque Orbweaver (Neoscona arabesca) Arabesque orb-weavers are, like any other orb-weaver, non-aggressive spiders. Only in rare cases, where the spider feels threatened, bites to humans or pets occur. The bite of an arabesque orb-weaver is not medically significant and the pain is mostly short-lived and comparable to a bee sting.
