Hello Bugman, you’ve helped me before with a Bristle fly a couple of years ago. Today I’ve seen 3 strange flies on my cherry tree, which is currently being attacked by the cherry tree slug. I suspect they could be feeding on it, but I’m not sure.
It’s Summer here in Australia and today was a dull humid day.

Robber Fly

Update:  December 16, 2012
Hi Daniel,
these are the best I could do.  I hope they give you enough information to identify it.  I noticed on the side-on shots a little white thing that looks like an egg on this fly.  Is that normal anatomy or has it been parasitised?  Just wanted to add, I didn’t harm any of the flies, they were all alive and well when I left them.  The cherry tree slugs were another matter though.
regards
Linda from Healesville

Robber Fly

Dear Linda,
Thank you for sending the additional requested images.  We originally thought this might be a Robber Fly and we maintain that opinion based on the beard visibly in the new photos.  Alas, we have been unable to identify this Robber Fly to the species level.  We believe the white object you refer to is a haltere, the vestigial wing structure of most flies.  Flies are distinguished by a single set of wings, unlike most winged insects that have two pairs of wings.

A friend of mine found this insect in her house. We live in country NSW, Australia. We thought it may have been a horse fly, or cicada or something, but not sure. If you could help identify it, that would be great! :) thanks.

Robber Fly

Hi Tiani,
This is a Robber Fly in the family Asilidae.  The closest match we could locate on the Brisbane Insect Website is the Giant Blue Robber Fly,
Blepharotes spendidissimus, though we cannot make out the distinctive halteres in your photoWe have a photo in our archive that we identified as a Giant Yellow Robber Fly, Blepharotes coriarius, a member of the same genus.

Found this inside my house last night, after recovering from a near heart attack I photographed and released it but would love to know what the heck it was as I have searched all australian bug websites and cannot find anything similar. It was approx 6 cm long

Robber Fly

Hi Caroline,
We are not sure if we will be able to provide you with a species name, but this is a predatory Robber Fly in the family Asilidae.  We frequently use the Brisbane Insect website to identify Australian bugs, but we don’t see any species there that look exactly like your individual.

When i saw this in the yard, i couldnt decide if it was a dragonfly or damselfly. The body and wings made me lean more to a damselfly but the eyes and shampe of its mouth didnt quite fit. Any clue as to what this insect is?

I found this big guy eating on a Carpenter Bee. He flew up to the Deck and landed on a chair carrying the Carpenter Bee.

Red Footed Cannibalfly eats Carpenter Bee

Dear GA BugHunter,
The Red Footed Cannibalfly or Bee Panther,
Promachus rufipes, is a formidable hunter that seems to prefer to feed upon large bees and wasps that it catches on the wing.  These photos are a wonderful addition to our food chain archive.
