Recently scientists found that a solitary ground-nesting wasp, the European beewolf wasp, harbors Streptomyces bacteria on its antennae and that the wasp uses these bacterial symbionts to protect the wasp larvae against pathogenic fungi.This would be a commensal relationship, where the wasps benefit, but the bacteria are not affected one way or the other.

Hey!I was looking for this answer myself. I don't know if these are caterpillars on your tomato plants (that is what I am experiencing), but according to the site referenced below, these white sacks are the pupae of the Braconid Wasp. The Braconid Wasp is a natural predator of hornworms (my type of caterpillar). Apparently, the wasp lays its eggs in the prey, and when the eggs hatch into larvae, they begin eating the hornworm's organs. The white sacks are actually the cocoons from which the wasps will emerge.Even though the caterpillar was eating my tomato plants, I feel really bad for it. I might put it out of its misery. I can't imagine something eating my insides when I'm alive!Source:http:/www.tammysrecipes.com/tomato_hornworms
The food chain would go, milkweed, monarch caterpillar, wasp.
mutualism
I'm not sure 'help' is necessarily the right word: wasps will capture caterpillars and feed them to their larvae.
Figs and fig wasps have a special relationship that is essential to their mutual survival. The fig provides a home for the wasp and the wasp provides the pollen that the fruit needs to ripen. The insect's life cycle begins when a tiny female wasp enters a fig and begins laying eggs inside it.
