Abstract

Juvenile Araneus expletus often place a visually conspicuous, disc-like white silk stabilimentum on one side of the retreat where the spider rests during the day away from its orb. Placement of the stabilimentum at this site rules out a prey attraction function and argues instead that it may function to defend the spider from visually orienting enemies.
