Just found one of California
Never saw one before and I am a native Californian. Came home from vacation and there was one of these rather large black and white striped bees dying in my house.


Moved from Coelioxys.

very likely Coelioxys (Cyrtocoelioxys) modesta
based on body form and above all conspicuous basal white hair band on T1

If indeed modesta, as I very strongly suspect, then it would be a new state record for Arkansas for subgenus Cyrtocoelioxys

not a leafcutter
a cleptoparasite of leafcutters

that is a fine point, i guess it does not actually do any leaf cutting of its own.

Not even close.
Have to forgive you for the assumption this is a wasp, but it is actually a female leafcutter bee in the genus Coelioxys. Check out the existing images in the guide if you don't believe me. They are parasites of other Megachilidae, so they don't have pollen brushes.

Oh hell
I could not make the wing veins work for the Sphecids at work. I don't keep the big book there. The overlapping abdominal markings seemed odd for a Sphecid. Someone has to keep you on your toes.

Shooter only lives 70 miles away from me. But I have not seen one of these.

well i was taken in... but after having looked through said genus, i admit defeat. thank you very much Eric.

Lovely animal. Any other angles on the wings or face?

nothing very good... i feel lucky i got any pictures at all as it was a very skittish wasp, if they are needed i can post some more pictures, but i would keep my expectations low as far as quality goes.

Why not post
Why not post another view or two for ID purposes, and you can later move any to frass that you aren't pleased with.

done... you may decide if any are worth keeping. i hope they are good enough to help.

I can't make out the hindocelli on your added shots. This may mean they are in fact deformed or mostly absent. This would put it in the Bembecine group. Your wing veins are good enough that once at home with the Bohart and Menke I can have a further look.
