Maybe this dude isn’t pollinating 15 floors up in the rain, but in the garden, yes. Wasps of all sizes are the main pollinators I see in my vegetable garden. I have my fair share of bees, butterflies, and moths as well, but wasps do double duty in the garden. Not only are they pollinators, but Braconid wasps will lay their eggs on hornworms and when they hatch, the larvae feed on the worm killing it. Instant pest control. And that is just one example of the over 200 possible pests that parasitic wasps control in a garden. Boom.
