Dear Bugman,
Can you please help identify what this bug is.
I live in metropolitan Sydney and I took a photo of this in my back yard. Its approximatly 1cm in length, shiny black with features that resemble a cicada, fly and a grasshopper. Can you help me know who my neighbour is. Thank you!

Ensign Wasp

Hi Damian,
This is an Ensign Wasp, and it really needs to be recognized as it performs a significant function.  Ensign Wasps parasitize the ootheca or egg cases of Cockroaches, though to the best of our knowledge, there have not been any studies on how effective Ensign Wasps are in controlling Cockroach populations.
