Black and yellow mud dauber, Sceliphron caementarium. I got a picture of one last year, but the lighting wasn't great. Now that I have a muddy pool in my backyard, I can see these guys every single day. But they're still hard to photograph well--very quick. I just saw on BugGuide that they are big spider hunters--bad news with the coming Arachtober. Their abundance may explain my complete lack of Uloborus this year.

For three weeks I've been trying to get a good picture of these guys. They've been visiting the place under my veggie containers, where the ample irrigation seeps into a thin layer of mud on concrete. But they move fast and don't like to be in focus. The background here is pretty distracting, but at least the wasp is in focus.

Mud daubers are solitary wasps and beneficial insects; female mud daubers hunt spiders, paralyze them and feed the spiders to their young. Mud daubers build their nests by gathering mud in their mandibles and applying it in layers. After dragging spiders inside the nest, the female lays her eggs on top of the spiders and then seals up the nest. Once hatched, larvae feed upon the spiders and when big enough, chew their way out of the nest.
