Ensign Wasp

Typically found indoors in buildings or outdoors in leafy litter where cockroaches are present.

Adults feed on flower nectar; however, the larvae are predatory and develop inside the ootheca (egg cases) of cockroaches.

They are easily identified by their small, flag-like abdomen which they bob up and down while walking. They are solitary and do not sting humans.

They provide a significant ecological benefit as a natural biological control against cockroach populations. They pose no risk to humans or pets.
