SteveJ I beg to differ.
I had an itchy foot one day and rubbed it with my other foot. Turned out it was a bumble bee and it stung me three times.
In the event that you think I talk crap......I found this on Wikipedia
"Sting
Queen and worker bumblebees can sting, but unlike a honey bee's, a bumblebee's stinger lacks barbs, so they can sting more than once.[19] Bumblebee species are normally non-aggressive, but will sting in defense of their nest, or if harmed. Female cuckoo bumblebees will aggressively attack host colony members, and sting the host queen, but will ignore other animals (including humans) unless disturbed."
Note the words "if harmed" Being stood on probably covered it:
