Small-headed Fly

Acroceridae sp.


This was a tiny individual (3 mm) - the head is disproportionately smaller than the bulbous humped body. These rather bizarre-looking flies are nectar-feeders.


Partly cleared remnant eucalypt forest (South Australia)


Apparently the Acroceridae are relatively uncommon. They are commonly known as Small-headed flies, Humpback flies, or Bladder flies.

I'm fairly confident this one is Ogcodes genus.

Your spotting has been nominated for the Spotting of the Week. The winner will be chosen by the Project Noah Rangers based on a combination of factors including: uniqueness of the shot, status of the organism (for example, rare or endangered), quality of the information provided in the habitat and description sections. There is a subjective element, of course; the spotting with the highest number of Ranger votes is chosen. Congratulations on being nominated!

Hello Kari Dawsonr and Welcome to the Project Noah community!
You dont have a location on your spotting,you have to edit the spotting again and put a location on the map window,ok?Thanks on advance:)
We hope you like the website as much as we do. There are many aspects to the site and community. The best way to get started is to read the FAQs at http://www.projectnoah.org/faq where you can find all the tips, advice and "rules" of Project Noah. You, like the rest of the community, will be able to suggest IDs for species that you know (but that have not been identified), and make useful or encouraging comments on other users' spottings (and they on yours).
There are also "missions" you can join and add spottings to. See http://www.projectnoah.org/missions . A mission you should join is the http://www.projectnoah.org/missions/2165... to chose the best wild photo of 2018,only the spottings added to that mission are eligible.Note that most missions are "local". Be sure not to add a spotting to a mission that was outside of mission boundaries or theme :) Each mission has a map you may consult showing its range. We also maintain a blog archive http://blog.projectnoah.org/ where we have posted previous articles from specialists from different geographical areas and categories of spottings, as well as wildlife "adventures".
So enjoy yourself, share, communicate, learn. See you around :)
