What's this stranger we've all seen?
Have you seen a black slender fly like creature with a hard shell like body, blue or green eyes, wings and an abdomen that looks somewhat detached from the rest of the body.
Yes, we've most likely seen it countless times, and that my friend is the terror of the cockroach world, the population controller of the cockroach world, the reason why you don't see cockroaches in every square inch of the ground. This my friends, is the Ensign wasp.
They get this name from the constant up down movement of their abdomen when they are at rest on a surface or while moving with their limbs on a surface as though they are signing constantly on a check book or a football jersey.
The larvae of the Ensign wasp is highly and completely parasitic to cockroaches.
The adult females lay a single egg inside the ootheca of cockroaches which house cockroach eggs too. The wasp's egg hatches quickly and the larvae consumes the cockroach eggs during it's larvae stage and emerges later as an adult wast from the egg case, isn't that way too brutal?. Well, it's nature.
The adults feed on nectar from the flowers of plants. They aren't in ant way harmful to humans as we are to them.
