Well, I'm the first to admit that caring for a child is difficult, especially during infancy, but if you think hauling around a diaper bag, stroller, and baby bottles is bad, just be glad you aren't a wasp mother, working to provide food for her growing youngster(s)!
I lucked out yesterday and captured this sequence of a female wasp pulling a spider she had caught, then paralyzed with her sting. She is taking the spider back to her nest - it's baby food, wasp style.
As Mama Wasp got to the edge of the breezeway, she dropped her catch to go ahead and scout the drop-off out.
For several minutes, Mama Wasp wandered around - up onto the flat surface of the breezeway, down the side of the concrete,...
A few final tugs, and Mama Wasp and her baby food were hidden from view.
Looking at bugguide.net, I am pretty sure that these wasps are spider wasps of the genus Tachypompilus. The information on this genus states that they are primarily found in open country (we qualify) and that they are often found nesting around (old) building foundations or in rock piles. Again, the habitat fits quite well.
These are "solitary" wasps, like mud daubers. The males have no stingers (which are modified egg-layers), so they can't sting. The females are too busy making nests, provisioning them, and laying eggs to bother with stinging. Typical of solitary bees and wasps, you seriously have to pick up a female or make her fear for her life to get her to sting you. She just wants to avoid any situation where her likelihood of dying increases, because as soon as she dies, her chances of reproducing are gone.
As a last comment, I found it interesting how Mama Wasp carried her paralyzed spider up the foundation wall: she backed up the entire way, and she appeared to be dragging it by holding on to one of its pedipalps (longish, arm-like mouth parts that spiders have in addition to their 8 legs).
Sometimes even I, the Luddite at heart, can appreciate modern technology!
