Black Flower Wasps ...
Black flower wasps are large, solitary, native wasps with iridescent blue wings.
The black flower wasp, Discolia soror, is around 20-30 mm long and has iridescent blue wings. Its legs are covered in short bristles. Male wasps are more slender than the females and have longer antennae.
These wasps are found throughout mainland eastern Australia and are often seen in open bushland and suburban gardens.
Black flower wasps are solitary and do not make communal nests. However, in mid to late summer, they often form small swarms flying low over an area of turf, a compost heap or around a shrub. The adults can also be seen taking nectar from flowers.
The adult females are large and powerful wasps and are designed to dig. They burrow into the soil to locate scarab grubs (from beetles such as the Christmas beetles), which they sting and lay an egg on. When the larva emerges, it feeds on the still living scarab larva which provides a fresh food source until the larva finishes its development. The adult wasp emerges the next season.
Female black flower wasps can sting but rarely do, as they are not aggressive. They can be useful predators of scarab grubs which are pests of lawns. They also pollinate native plants.It is not necessary to control them.
