Argyrodes spiders are kleptoparasitic. They live in the outer edges of other spiders' webs and move in to steal prey when the coast is clear. Apparently the method of at least one species (Argyrodes nephilae) is to attach a line of silk then cut the wrapped prey out of the host web. The bundle swings free and can be taken to the outskirts of the main web to be eaten in relative safety.
