Please, can somebody confirm if this specimen is a Trupanea amoena?

The image is taken in Antofagasta, Chile. The specimen is fed on nectar of the flowers.

Thanks

Please find the attached image.

Nope, that didn't work. Either put the photo on a server accessible by us all or, even better, try attaching it to the post. Read the FAQ if you don't know how.

Roden, if you can see the image from the link, it is probably because you are logged in for that particular site. It will not work for those who are not logged in. Plz, follow Crex' suggestion.

I have corrected the error, please, respond my question.

Hi Roden,

Well it looks like a Trupanea, and no doubt it is a Trupanea, but it's not T. amoena.
T. amoena does not occur in South America, there are however 58 other species to choose from, ehhh sorry 59, Daniel Frias described another one just last year.
So I think it will be dificult to get an idea on a photo only.
Good luck with the efforts!

Hard work.

Really, the only difference that I can see, is the green eyes. Lamentably, my camera does not allow better photos.

---

Sorry, is Trupaena o Trupanea? In a local site -in Chile- it say Trupaena.
Which is the correct form?

---

Trupanea is correct. There is no Diptera genus names Trupaena according to the BioSystematic Database of World Diptera.

Edit: PS. Best wishes to the city. I have some great memories of Antofagasta which I visited in early 1990s.

Hi Roden,

In most cases the colour of the eyes in most Tephritids is splendid green, all a matter of light I guess whenever eyes appear more reddish. Or when they have died the green colour of the eyes vanishes.
If you look at the picture of T. amoena in the picture gallery, indeed it is Trupanea (Trupaena is surely a misspelling!), and you compare it with your specimen here you can see that for a start the number of dark radials from the dark marking is different in both species, besides the radials in your species are much more uniform than in T. amoena.

Really, the marks are different.

They know some other Web site where can find more images of this sort?
I need to make a report on the insects that populate my city, and do not want to commit errors in its identification.

The Chilean sites are not of much aid.




Thanks, Kahis, my City is 50% greater, and more beautiful, than in the 90's... B)

but I am disoriented now, because I have noticed that there are specimens with green eyes and yellow eyes, although with the same dark marks in the wings.
It can be the color of eyes sexual dimorphism?
Nevertheless, never I have seen reunited exemplary with different color from eyes.

---

Hi Roden,

Nope. to my knowledge the colour of the eyes is not sexually dimorf, but rather a difference in the way the light falls on the lenses and reflects.
