Are food web woven by spiders and caterpillars?

Interestingly enough, webs are made by both caterpillars and Spiders. Tent caterpillars create web-like nests in trees that resemble tents. These silken nests protect them from predators, and also allow them to feed on the leaves of the tree. Spiders also make silken webs. These are typically closer to the shape most often associated with webs. Most spider use their webs to trap their prey and eat.
