Unidentified

I have been watching this spider for over a week now. It only moves to be under or near a tomato flower where it catches wild bees. I have another photo of it with a different fly I will post. It doesn’t seem to go on to the tomato flowers. It is almost the same colour so great camouflage. I can’t see any “mate” & no real web although it look like some sort of sticky stuff on the leaf in this photo. I am hoping it can be identified.
