I saw this creature on a wall being eyed by a gold dust day gecko as a possible meal. Eventually the gecko thought better of it, which is probably just as well. This is a sphecid wasp and they can pack a sting, though they aren’t aggressive.
From searches on whatsthatbug.com and bugguide.net, it appears that this sphecid is in the genus Prionyx, probably P. fervens.
