Ensign Wasp

Found globally in urban and suburban areas, particularly near buildings or where cockroaches are present.

Adults feed on nectar and honeydew; larvae are specialized predators that consume the eggs of cockroaches.

Notable for their unique flag-like abdomen which they pump up and down while walking. They are solitary wasps and highly active during the day.

Beneficial to humans as they act as a natural biological control for cockroach populations; they do not sting or bite humans.
