Hi, I am pretty sure this is a common insect, but no one knows what this is. I will appreciate if you could tell me what this is. Thanks!

Emerald Cockroach Wasp

Dear Huaguang,
Despite the lack of clarity in your photo, we are certain you have submitted an image of an Emerald Cockroach Wasp,
Ampulex compressa, which we recently featured because of its amazing life cycle.  A female stings an American Cockroach, turning it into a zombie that can be led back to the nest where it becomes a meal for the developing wasp larvae.  There is much online information available on this food chain relationship.

Thanks for the information. It’s such an amazing insect, especially in a country where cockroaches are absolute pests. Unfortunately I hardly see them at all!
