Hello,

I'm stuck with this one! I rescued it from the pond, it cleaned itself up on on my finger but it only had one wing. :|

18th May 2010, near Lincon UK. Not the best photos but I was using one hand.

3 pics.

Janet :)

pic 2

pic 3

---

Always best to use both I find! :P
Chloropidae, I think it looks like Oscinella sp.

---

I think you're right Roger, about Chloropidae Oscinella that is.

I thought it looked Chloropidae-ish but for the last two nights I have been not able to get through the bogged down phone lines to check on things so in frustration my mind went blank. Apparently Xmas is around the corner, or down my internet line. :P

---

Dear Janet
Is first picture same species of 2 and 3 pic.s or it's cause angle? I think that's different from 2 and 3 pic.s!

---

Hi Sara, yes they are all the same fly taken at the same time. The first two pics I took while it was on my finger, that's the pink background! :D I then placed it on a stone for the third pic.

---

Unless you are being plagued by one-winged Chloropids?

---

That's good :D
It seems O. pusilla, but for positive ID, need to ganitalia of mail...
Do you rubbing any thing your finger for fly? B);)

---

Thank you Sara, a near ID is better than not.

No I didn't put anything on my finger, I had taken it out of the water in my pond. I'm always rescuing tiny insects!

---

If you have the specimen, check for the large ocellar triangle on its head. If it lacks that feature, it could be in the family Camillidae - which have a lustrous sheen to them, which your's appears to have?

---

Hi
would you please tell me number of characters about Camilidae?
I don't have enough inform about them?

---

It does appear to have the triangle Nigel, I didn't keep it even though it had only one wing. I'm too soft to do that. ;)

I should have recognised this as one I posted here not so long ago which looks to be the same but with two wings, it was only 5 days before this one.

Sara, I found the characters of Camillidae for you..

http://delta-intk...millid.htm

http://en.wikiped...Camillidae

I lightened a pic to show the triangle, there looks to be a row of bristles at the side of it showing on one of the pics.

---

Oh yes, the triangle appears to be there. It's difficult to be sure but I can't make out any plumosity on the upper side of the arista, which would eliminate Camillidae.

---

In this pic I could almost imagine there is plumosity on the arista..

---

But the costa doesn't appear to have two breaks, there looks to be one..

---

Thank you very much Janet!
With these interpretations I think it's same Chloropidae?!
Doesn't it??

---

I think the two flies are the same species, the one in this thread maybe is a male?

The fly in the earlier thread suggests a female because of the abdomen.

http://diptera.in...d_id=35134

Unless of course it's the same fly and it had laid it's eggs thus shrinking the abdomen! The abdomen of the fly in this thread does look narrow and small like a male's to me.

---

Oh! I be doubtful about Chloropidae!
Do you have any pictures about genitalia from under of abdomen??
I have some pictures, but they are large size for forum, please wait until I set them, to I can say why?

---

Sorry, these are the only pics I have. Waiting to see why it's not Chloropidae.

---

Again Hi
In Chloropidae, usually we can see genitalia easily, in male and female too.
This is a kind of female genitalia in Osinella sp. (sorry for too bad my pictures)



And this is a mail genitalia in Osinella pusilla



It's my think! What do you think?? :)

---

I see what you mean! Photos can be deceiving though, and the wing venation does look to fit Oscinella.

Closer shot of the male..

---

About wing venation and other characters I'm agree too, but about genitalia, that's difficult..!! I hope which it be Oscinella pusilla?

---

I couldn't say which species it is Sara, I read that the antennae and tibia colour separated it from O. frit but there seems also to be confusion with some of the species in this genus.

Some species of Chloropidae are difficult identification, for example
Females of genera Lasiosina and Meromyza are very difficult also if we poses males, the same with Aphanotrigonum. It is nearly impossible to identify Oscinella species, except some few species. No revision exists, and the variability of leg colour is very big, dependent on the temperature under which the larvae grew up. (For example in O. pusilla all of tibia(s) are yellow that mid and hind tibia have dark-brown spot in middle (part) it and etc…)
Main character about them is the same of male genitalia….
About your forum:
http://diptera.info/forum/viewthread.php?thread_id=35134
I can almost sure about it, but in this forum, profile is not clearly well… :|

---

There certainly seems to be no break in the costal vein near the humeral cross vein, so that eliminates my suggestion of Camillidae.:(

---

Well it has all been very educational anyway Nigel, I now know what to look for should I come across a Camillidae. We have not got that family in the Gallery yet!

---

Yes, these threads are great for learning more and more about flies!

---

here one Camilla sp.

I found that one too jorge, I was looking for a fly I had and thought it might be Camilla but I only have one shot from above the head frontal view. The pattern on top of the head looked very similar to Camilla, but I decided in the end mine was Piophilidae.
