African spiders in the genus Stegodyphus are social spiders that build communal webs. The spiders can cover a larger area with their prey and as a group, be more successful than as individuals. The store of captured insects can be an attractive food source for other creatures to exploit. In 1903, Entomologist R.I. Pocock reported caterpillars of the moth, Coccidiphila (formerly, Batrachedra) stegodyphobius crawling along the strands of the web and feeding on the spider’s prey. The caterpillars pupate in the web, a site that provides protection against predators. The moths were observed flitting about the sticky web without becoming entangled. Coccidiphila stegodyphobius has adaptations that keep it from sticking to the web, and exploit the spiders for both food and protection.
