Ensign wasp

Often found indoors and around buildings, especially where cockroaches occur; also lives outdoors in sheltered areas.

Adults feed on nectar and other sugary substances. Females lay eggs in cockroach egg cases; the developing larvae consume the eggs.

Recognizable by its tiny, high-set, flag-like abdomen and long legs. It is solitary and generally wanders or searches for cockroach egg cases rather than bothering people.

Harmless to people and pets; it helps suppress cockroaches. Image detail is limited, so identification is based on appearance.
