I remember i held one of thoes bees. It never stinged me, instead it sat on my finger.It was one of the most beautiful bees i had ever seen. Then it flew away. But i saw it did have a stinger so have 911 on speed dial, just in case.

Here is a picture of a Cicada Killer Wasp:
Here is the link to a website with information on them:http://www.ipm.iastate.edu/ipm/iiin/bdigwas.html
The website says that they sting if handled but the one that i held had a stinger but didnt sting.
