Spider parasite fly (♂)

Leucopsina odyneroides


Body length about 10mm. Small head with all-encompassing eyes. High domed thorax. Very large calypters.


On Leptospermum or Kunzea sp. flowers at the edge of a local national park.


This fly is so similar to a 'potter wasp', which appears at the same time of year, that I think there must be some mimicry relationship. All suggestions welcome on that subject! See wasp here....
subfamily: Panopinae
To the owner of the Hymenopterans mission sorry but a bug is stopping me from removing this spotting. I'll keep trying.

I left this spotting blank to see how many people might think it was a wasp (or a bee) but there's no tricking you guys. :-)
Jolly you're right those calypters are a big giveaway.
Bayucca I think your ID is spot-on. Not much info around on them though.
I'll be wracking my brain for days now about why it looks so much like a little wasp that appears at exactly the same time.
Thanks for the comments and suggestion.

Acroceridae. Leucopsina odyneroides as closest and very cheeky suggestion! Please, verify!!
