Here is Southern Oklahoma, the red wasp is very common. We also have yellow jackets, honeybees and bumble bees. I have been stung by the yellow jacket, honeybee and the red wasp and have to say the red wasp is the most painful.
I was weed-eating around an old boat we have behind the barn and apparently struck a nest of red wasp. They swarmed around me as I began to run backwards. Only one was able to catch me, thank God! It felt as though someone stuck a hot match to my arm, but the pain doesn't last long.
I stepped on a honeybee once while walking barefoot in the grass. That stung, but not as badly as the red wasp and again, the pain was short lived.
I was picking up a pair of my daughters shoes she had left outside one day, and as I ran my hand into her shoe, there was a yellow jacket inside. That was quite a surprise!
Great picture of the red wasp by the way! :)
