Rubrica surinamensis (DeGeer) is a large and striking neotropical wasp belonging to the family Bembicidae. Its geographical range extends from the Argentine to Trinidad. It is commonly found nesting gregariously in a semi-social manner with other individuals in areas of bare sandy ground exposed to the sun. Flies of many different families comprise the prey. The flies captured are stung to death and used for provisioning the nest, the developing wasp larva being fed progressively from day to day.
