Hi,

I think eyes have short hairs, which would indicate Hebecnema vespertina. Is it possible to confirm the ID?

looks ok to me. eyes sparsely haired, two av on t3, yellow knob of haltere. just be sure that there is no prealar. I think H. vespertina is a good match. If there is a problem with this id, then Nikita will weigh-in on the matter.

Thank you. Smile The next picture is not very good, but I don't see the prealar.

I agree with John and Nini on Hebecnema. But why vespertina? H. umbratica, I'd say.

Then it must be H. umbratica. Thank you Nikita.
For me, i thought the eyes are toucjhing and more hairy for H. umbratica. I can't see two pd on the mid tibia so i assumed they are not present. My apologies.

John and Nini.
1. Eyes are hairy (rather short and sparsely, but doubtless), while in vespertina they are really bare.
2. In Moscow region, vespertina appears in late May and normally disappear till July.
Porto is 41N (Moscow 56N) and on seashore, at 20 July. I do not think that vespertina present in Portugal at all. In contrast umbratica goes very far south (till Vietnam, for example, or till Morocco), so their presence in Portugal is quite natural.

Hello Nikita and i hope that you are having a good day Smile

i remember now that i have notes about Hebecnema that i gathered from your posts. I aslo admit that have said this to me before about the time of year. I need to read your notes more often. My apologies. I get lazy sometimes.

Before i forget, i will send a pm to you now. I want to ask you about a book.

Thank you for correcting me,
John

Hi Nikita, the hairs on the eyes of this specimen are really small and very difficult to see. I considered that they do not fit H. umbratica because in April I caught another Hebecnema that I identified as H. fumosa which has very long hairs on the eyes (see next picture). Later I'll post more pictures of this specimen from April in a separate post. Which characters do you need to see from this specimen to be sure of the species?

Hi Rui.
You are right: fumosa has eyes morehairy than umbratica. Also fumosa's eyes are more reddish while umbratica's - bronish. H. fumosa is bigger. Both these species are very predictable for Portugal, so I suppose your identifications are correct.

Thank you Nikita. Regarding H. umbratica, one thing that led me astray was that in the key it says that this species has silvery parafacialia and I thought that in my specimen it was not like that.

I decided to pull the genitalia a bit. Comparing to the pictures in the following links, I think it is most similar to H. vespertina. Nikita, what do you think?

I never examined genitalia of Hebecnema, drawings in books look similar.

Jewelm699 - did you upload it to a forum (which one?) or the gallery? I can't find it.

11.09.19 13:15
I’m hoping someone can identify the phoridae maggot or pupae I just uploaded.

Rafael p is legs and f1 is fore femur

If you experienced a very sluggish site recently, it may have been because someone tried to upload a maliciuous script by force. It appears to have failed. The visitor was blocked further access.

@Paul Beuk Thanks mate!! Best wishes!

Where are the meaning abbreviations of Lindner's series Die Fliegen der Palaearktischen Region, ie. f1: anterior femur, ...and what about "p"? (I don't possess volume I)

17.07.19 19:37
Yup, you can view the wing from above (dorsal side) and from beneath (ventral side).

16.07.19 13:31
Hey Dipterists! Quick Question: Vein r2+3 bare beneath. I've always assumed that this is below as in when you look at the wing flat. Am I right? Thank youuuuu! Pfft
