What happens when one species of spider accidentally falls into the web of another species?

Weeeel, depends, according to the staff bug guy at our sister institution, Consolidated BioAlice. Spiders are cautious and generally sure-footed. They have oily secretions on their legs and toes to keep them from tangling in their own webs. (And not all strands in a web are sticky.) Also, most spiders will steer clear of the competition. But field observations suggest a large spider caught in a small web can probably extract himself and depart. Vice versa, he could be lunch.
