For almost a year now I have been trying to identify this fly. Still, I have not found what species it is. My guess is that it belongs to the Ulidiidae, but I am not sure. Does anyone have an idea what species this fly could be? I photographed it in the Republic of the Congo

Possibly Picture Winged Fly

Dear Daniel,
We agree that this could be a Picture Winged Fly in the family Ulidiidae, but we would seriously consider expanding the possibilities to include the superfamily Tephritoidea that includes Ulidiidae.  The perspective of your image, while quite artful, is not ideal for identification purposes if considered alone.  We once recall reading that four different views are helpful in identifying Robber Flies:  dorsal, lateral, head showing eyes and one other view that currently escapes our memory.  Alas, we cannot locate where we read that.  Furthermore, while quite pretty, many small flies do not command the same attention as large and showy butterflies, moths and beetles that are all much better represented on the internet.  Species from Africa are far less well documented on the internet than North American, Australian and British species.  We feel if you are only depending upon the internet, exact species identification based on this single image might not be possible.  With all that stated, we are posting your gorgeous image and we appeal to our readership to provide comments with any suggestions they may have.

Hi Solene,
This reminded us of a Fruit Fly in the family Tephritidae, so we searched iSpot for South African species, and though we did not find an exact match, we did find several images that looked very similar, including this iSpot posting, though it is only identified to the family level.  The common name for the family in South Africa is Picture Winged Fly, but that same name is used on iSpot for the family Ulidiidae as well.  We are confident that in South Africa, Picture Winged Fly is an appropriate name for your individual, though we cannot say for certain to which family it belongs.

I photographed this little guy at a place called Crystal Lake, about 50 miles outside of Denver, Colorado. I really love his eyes. Can you tell me what he is please?

Fruit Fly

Dear Ornithocheirus,
Based on images posted to BugGuide, we have identified your Fruit Fly as a member of the genus
Paracantha, however the three species listed look remarkably similar and Colorado seems to be within the range of all three species, so we are reluctant to go further than identifying the genus.

Hey Bugman!
I have been finding large numbers of this mysterious (but beautiful) fly in my front yard… I’ve done a lot of internet research and cannot for the life of me figure it out… Is it a Robber Fly??? I have found them all of my Armenian Basket Flower and Artichoke… Please help! I need to know if it’s a pest or not.
Thanks,

Mating Artichoke Flies

Mating Artichoke Flies

Dear Matt,
These are most certainly not Robber Flies.  This is an introduced Artichoke Fly,
Terellia fuscicornis, a species of Fruit Fly.  Your images of a single individual are both females, as evidenced by the long ovipositor, and the image with the three flies include two males that are attempting to mate.  Interestingly, bugGuide only has images of female Artichoke Flies, and they do not provide a common name.  There are many nice images on the Natural History of Orange County site.  As an introduced species, they may pose a threat to cultivated artichokes, but we have also found information that they use Milk Thistle, an introduced pest weed in California, as a host so the jury is still out if they are an agricultural pest or a biological control agent.

Hey Daniel,
Sorry for the delayed response – I saw and read this e-mail and had to do something else. I forgot to write you back to thank you, but I really was so impressed with your knowledge and how thorough your response was! Thank you so much – very informative. I really appreciate it.
Keep up the good work!
Thanks again,
Matt

Hi,
I have a couple of flies that I haven’t been able to identify.
The first I thought would be easy, however, I’m coming up empty! I’ve Googled lots of phrases, and gone through the photos on here (I think I hit them all), but didn’t see any matches. This one was in late June of 2010 in the Garden of the Gods in Colorado Springs, CO.
The second and third are of the same insect. I believe is a picture-wing fly, but it could also be a fruit fly, as it’s a very tiny insect. This one was in late May of 2012 in Red Rocks in Morrison, CO.
Thank you so much for your help! (Also, your book is fabulous!)

Fruit Fly:  possibly Aciurina trixa

Fruit Fly: possibly Aciurina trixa

Hi Amy,
Thanks for the compliment and we are happy to hear you enjoyed The Curious World of Bugs.  We believe your second fly is a Fruit Fly in the family Tephritidae, not a Picture Winged Fly.  The closest match we were able to locate on BugGuide is the Bubble Gall Tephritid,
Aciurina trixa, though the pattern on the wings of the single individual posted to BugGuide is a bit different.  The photographer did make this note regarding an unpictured species in the same genus:  “This keyed to Aciurina bigeloviae in the excellent 1993 reference by Foote, Blanc, and Norrbom(1), and everything fit well (e.g. descriptions, wing diagram, location, host plant). Foote et al. mentioned that two other species had been synonymized with A. bigeloviae by Styeyskal in 1984, and that this was the most widespread and commonly encountered species of all the Chrysothamnus-feeding Aciurina…as well as the most variable. (In fact, the detailed synonymy and references for A. bigeloviae take up an entire page in their book!).”  So, we believe we have the genus correct, but the species remains questionable.  Your individual is a female based on the presence of the ovipositor.

Dear Josh,
Your photo isn’t that sharp, but based on this image from BugGuide, we believe this is a Fruit Fly,
Eurosta comma.
