The Goldenrod is a bitter astringent and relaxant herb that reduces inflammation. However, this wasp here finds its pollen specially soothing.

I had stopped to have a drink on my walk when this beautiful insect landed by my feet.

 

The black flower wasp, Discolia soror, is around 20-30 millimetres 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.

Adult wasps 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 beetle), which they sting and lay an egg on.

When the larva emerges, it feeds on the still living scarab grub, which provides a fresh food source until the wasp larva finishes its development. The adult wasp emerges the next season.

Black flower wasps can be useful predators of scarab grubs which are pests of lawns. They also pollinate native plants.

 

Female black flower wasps can sting but rarely do, as they are not aggressive. It is not necessary to control them.

Discolia soror, also known as the blue or black flower wasp.

Thank you very much for the visit and comments. Cheers.

However, in mid to late summer, they often form small swarms flying low over areas such as: turf, shrubs and compost heaps. Adult wasps can also be seen taking nectar from flowers.

The blue flower wasp is many times larger than the bee

Thanks to Gerry (*Ryn*) for the I.D.

A very interesting species of wasp. The adults feed on nectar, however the wingless female burrows into the ground and parasitises beetle larvae and mole crickets, laying her eggs on them.

I was fortunate to find this couple in nuptial bliss before they flew off to enjoy their wedding breakfast in a flower somewhere. They are important pollinators of native plants.

The females are sometimes mistaken for ants and in fact one species has the common name of 'blue ant".

Yorrick identifies this as "Scoliidae, Hymenoptera" but now that I do some research I think this is the black flower wasp, Discolia soror
