Anoplophora graafi
It may look like a cockroach, but it is not. This guy has a blue head while cockroaches have a head that is nearly invisible from the top down. You might need a magnified image of the insect so you can see its head.
Roaches have two pairs of wings that are papery or leathery, while beetles have a hard outer pair of wings that protect the flying wings underneath. So there is no need to yell “Cockroach!”
