Telostylinus angusticollis
Neriidae is a family of true flies (Diptera). Some species are known as cactus flies, others have been called banana stalk flies. Telostylinus angusticollis is the only representative found in South Queensland. Yellow and black body, striped long legs, distinctive mouth parts and and aristate type antennae with orange pouches.
Tree bark, subtropical suburban garden.
The following info is taken from http://www.bonduriansky.net/neriidae.htm... "Neriidae is a relatively small family of true flies (Diptera) with long, stilt-like legs. Most species are found in the tropics. Neriids have very interesting behaviours, and many species are strikingly sexually dimorphic, with males having much longer legs, heads and/or antennae than females. Like piophilid flies, neriid larvae have the ability to leap during the stage just before pupation when they migrate from the larval feeding substrate to the pupation site. Very little research has been done on this interesting group of flies." Two neriid species are known in Australia: Telostylinus angusticollis is native to NSW and south Queensland. These large flies (up to 2 cm in length) aggregate and breed on rotting trunks of Acacia longifolia. T. angusticollis is a particularly fascinating system for research on environmental effects on body size and shape (i.e., phenotypic plasticity and condition dependence). Flies reared on low-quality larval medium exhibit little or no sexual dimorphism in body size or shape, whereas males reared on rich larval medium exhibit extreme elongation of legs, head and antennae relative to females. The four flies pictured below are full-siblings (males on the left, females on the right) that were reared on larval diets of varying quality. Telostylinus lineolatus inhabits tropical north Queensland, where it aggregates on flowers and rotting fruit. These flies are much smaller than T. angusticollis, and much less sexually dimorphic, particularly in head shape. Neriids can be reared in the lab on an artificial medium consisting of molasses, malt and soy protein mixed with hydrated 'cocopeat' (shavings from coconut husks). The have a generation time of about 30 days at 26 C." See also: http://www.webcitation.org/5y9cPNkDI
Thanks for your further comment Sukanya! Comments can fly very fast on Project Noah :-) It was the first time for me too noticing this fly.
Come and visit Borneo. There are so many undiscovered species you will get to see for the first time and will never be seen again in the future :-)
Yes, I did see that. I was so excited to see this fly again..when I had first spotted it I had no idea what it was. It wasn't till my fellow spotters on PN identified it for me that I came to know it as the Banana Stalk Fly and I just wanted to tell you...I think bayucca's comment was just moments before mine...I read it only after I had clicked on Post Comment.
We have a belief in India that if you see something for the first time , you will see it again very soon....
I have to amend my previous comment: not one but two neriid species are known in Australia: Telostylinus lineolatus and Telostylinus angusticollis. Only Telostylinus angusticollis is native to South Queensland (see notes)
If you check bayucca's suggestion you'll see that they are, Sukanya: same genus, Telostylinus.

Looks a lot like my spotting of the Banana Stalk Fly...may be these are related.
That was fast even for you! This seems to be the only species of Neriidae found in Australia. Thanks Domi! I will add the info I found.
Neriidae, looks like being Telostylinus angusticollis. Please, verify, I actually have no IDeas about flies ;-)...
