Our regular mud daubers are pretty docile. Our regular ones are larger than the one that stung me, and they are brown. i can work around them without issues. I followed your links, Toni, and now I'm pretty sure this was Sphex pennsylvanicus, a black wasp. Different sites said the sting is one of the most painful of all insect stings. Yep. It was. Today, a full 24 hours later, it is starting to swell and itch. One website noted that these wasps are important pollinators, and they really love mint. aaaaargh...I just planted mint in every combination planter! I bought 8 different flavors. The pots are right up next to the house by my comfortable reading chairs. Guess I'll be repotting some planters!
