Cockroach Wasp, Asian Cockroach Wasp (likely)

Natural Habitat

Typically found in tropical and subtropical regions. They are often associated with human dwellings and gardens where their cockroach prey can be found. The specific species in the image appears to be an indoor inhabitant or wanderer, possibly attracted to lights.

Diet & Feeding

Adult wasps feed on nectar and honeydew. The larvae are parasitic, feeding on paralyzed cockroaches provided by the mother wasp.

Behavior Patterns

Cockroach wasps are known for their unique predatory behavior. The female wasp stings a cockroach twice: first in the thorax to paralyze its front legs, and second in the brain to induce a docile, 'zombie-like' state. She then leads the cockroach to a burrow, lays an egg on it, and seals the burrow. The hatched larva consumes the living cockroach.

Risks & Benefits

Risks: Generally considered harmless to humans, as they are not aggressive and stings are rare, usually only occurring if provoked. The sting is not medically significant. Benefits: They can be considered beneficial in some contexts as a natural biocontrol agent for cockroaches, helping to regulate their populations, particularly in tropical environments.
