Jewel wasp (Ampulex compressa),

Jewel wasp (Ampulex compressa), a solitary wasp of the family Ampulicidae mostly found in the tropical regions of Africa, South Asia, Southeast Asia, and the Pacific islands.
It is known for its unusual reproductive behaviour, which involves stinging a cockroach and using it as a host for its larvae.

The wasp is mostly found in the tropical regions of Africa, South Asia, Southeast Asia, and the Pacific islands.[1] The flying wasps are more abundant in the warm seasons of the year.

A. compressa was introduced to Hawaii by F.X. Williams in 1941 as a method of biocontrol. This has been unsuccessful because of the territorial tendencies of the wasp, and the small scale on which they hunt.[2]

The species is also found in the Brazilian states of São Paulo and Rio de Janeiro.[3][4] A. compressa likely arrived in the country through the ports of Santos and Rio de Janeiro.
