Are all wasps and hornets a threat to bees?

[qa33010]

This is the first wasp or hornet I've seen in about a week and it is digging a hole right in front of my colony.  It is about one to two inches long with black, orange and yellow coloring.  I can't find it on line.  The closest I've been able to find is the Cicada Killer Wasp, but not close enough.  Does anyone have any ideas?  Thanks!  David

One of those mud daubers maybe? But they don't dig holes.

Is this close?

No it wasn't a dauber.  The face was the pale yellow.  At first I thought Pale-faced hornet but I don't know what one looks like.  

Jerrymac!

    I can't get a good look at the picture, but, except for the head that is real close.  I have pix and will get them to Wal-mart tomorrow and if they let me I will post one.  I have trouble with their pix disks loading up.  Usually they're just usless, but fast.

Oh oh!  I didn't see the second one.  That looks dead on!  Thanks!

FOUND IT!!!  It's called the Great Golden Digger Wasp.  I saw a picture of it here.
