It's not actually an emerald cockroach wasp or a jewel wasp.
What they have here is a species of parasitic cuckoo wasp (also sometimes referred to as an emerald wasp)
The Emerald cockroach wasp belongs to the family Ampulicidae whilst this cuckoo wasp in the picture is actually in the very large family Chrysididae.
As to what species specifically I am not sure as there are over 300 species.
