Black Flower Wasp

I saw one of these earlier in the week but I had no chance to stop and track it.

But today I had the pleasure to get up close to this Black Flower Wasp (Scolia soror).

I don't remember seeing one before.

Some information garnared from searching...

They tend to be solitary.
They come out during summer.
They are not aggressive.
The adults feed off nectar & assist with pollenation.
The eggs are laid upon grubs of a species that damage the roots of plants. The wasp larvae eat these curl grubs.
The metallic look with beautiful blue tinted wings.
The wasp is about 3cm long (1.1811 inches)
