Hello,

Bellardia have 2+3 ac brsitles.

Best wishes,

Number and position of thorax bristles as well as its short stripes close to the head match Eudasyphora (Muscidae) that can be greenish as well as bluish. The eyes are densely hairy, so E. cyanicolor is no good match. The two other species can be discriminated by the bristles on the mid tibae:
E. cyanella: no accessory setae above strong anterodorsal seta on mid tibia
E. zimini: 1-2 accessory setae above strong anterodorsal seta on mid tibia
That is difficult to see in your photos, so "Eudasyphora spec."!
Regards, Sundew

PS. I think Bellardia has also bare eyes.

---

Thank you all for help

---

Good point. “ All” Calliphorini have bare eyes. [Yes, I know, not true in Australia]. Theo

Hello Drosera,

E. cyanella: no accessory setae above strong anterodorsal seta on mid tibia
E. zimini: 1-2 accessory setae above strong anterodorsal seta on mid tibia
this is not your work, sundew. I doubt that you would know the difference between them without keys from experts.

many Tachinidae have hairy eyes too, so why you looking at the unobvious? the thorax is your simple and quick route away from the proposed family of Calliphoridae.
'She who can does; she who cannot, teaches.' do you agree botanist Dr. Brückner? I believe that you once taught botany at a university. interesting.

Hello Theo,

Are you sure that you can recognize a Bellardia, Theo? I really wouldn't trust your opinion about Muscidae at any level.

I didn't see botanist 'sundew' recognizing Pollenia in that post. Not enough books for her to plagiarize, i guess. She's too busy reading British keys from S. Falk.
Sadly, vagabunda is one of the easiest Pollenia to recognize.

Best wishes,
John

Hello John (and possibly the others)

I am still confused. I checked pictures of Eudasyphora species and I think, they look much more "metallic" than the one on my pictures. I have to admit that my fly looked even less metallic in the field and bluish color became apparent after picture processing.

Meanwhile, I photographed this one at the same place (Slovakia, Carpathians, Banska Bystrica, forest clearing, 700 m.a.s.l., 28 April 2020) this fly and I am wondering if this is the same species.

---

My untrained eye cannot see any difference except color. Maybe I should go back to Syrphidae :)

Hi Treebeard,

I didn't post a possible species because i don't see Eudasyphora and i am too busy programming a search engine for my website.
Also, several members of this site disrespect me and my opinion consistently, so i stopped offering my opinion.

sundew fails to notice the tessellations on the abdomen, which are not characteristic of Eudasyphora. The eyes are densely haired which also leads away from Eudasyphora.

I believe that you have a female Dasyphora pratorum but you should wait for an opinion from Nikita Vikhrev. Nikita is a Muscidae specialist. I recommend that you change the title and wait for a reply from Nikita.

Best wishes,
John

---

Thank you very much. Is your website already available?

---

Hi treebeard,

not yet. I just rewrote my file system code to make my site completely virtual (no actual folders/files other than images and text data files). I tried to make an operating system style desktop with a file explorer/manager. I am successful despite not knowing that code. I've also added language support and a bookmarking system. I just need to finish my search engine and add some final security measures. I hope to be finished by end of May.

Best wishes,
John

Best wishes as well

John, take it easy! Be less nervous! Especially so, because I think you are right, I
also think it is Dasyphora, D. not albofasciata.

---

Thank you, Nikita, spasibo!

---

Dear Matej.
without being responsive to John's offending allegations, I just want you to know that I got the information on Eudasyphora from the valuable forum archive - one cannot read enough in the old threads! In this case, here: https://diptera.i...d_id=42488.
Regards, Sundew

Dear Drosera,
Hennig (1963) regarded all species mentioned above as Dasyphora. Afterwards the genus was divided into two:
Dasyphora (with less distinct metallic shine; densely dusted body and with always hairy eyes) and Eudasyphora (with strong metallic shine, few whitish dusting and eyes hairy or bare). This circumstance often leads to misunderstanding in which genus one should identify a specimen of (Eu)Dasyphora.

---

Nihei and de Carvalho (2007) proposed re-synonymizing Eudasyphora with Dasyphora based on a phylogenetic analysis.

---

I'm not surprised

---

Thanks for the explanations, Nikita! Yes, I know the paper by Nihei & de Carvalho (2007) (it's here: https://academic....93/2630914), and there is also a subsequent one by the same authors (2009, https://www.resea..._Diagnoses. They treat Eudasyphora as subgenus but, as it seems to be not monophyletic, demand further studies to verify or merge the subgenus. Does anyone know a more recent study on this subject? I wonder why GBIF and Fauna Europaea still maintain Eudasyphora as a genus...

Dear Johnes
How are you doing ? I am asking, because you seem to be very grumpy, lately. While I welcome your knowledge in Calliphoridae and other families, I don't welcome your tone with personal attacks. Feel free to comment or even criticize on any post I ever made, Popper rules ! But there is no need to make it personal. This forum is for friends of Diptera, and I stress friends. If you want to quarrel or pick a fight, there are many more suitable places all over the internet available.
Your recent tone of voice is in my opinion unnecessary, please don't do that. I will report them as improper to the webmaster. You might consider rewriting your contributions, in which case I will be happy to delete this post. In the unhappy event you continu your aggresive tone, I will continu to report these posts.

Stay healthy and be happy :)

Theo

Hi Nikita,

I hope that you are well. Thank you for confirming Dasyphora. I'm happy that Matej has a proper id for his flies. I have not examined Dasyphora yet, so all of my knowledge of this genus is attributed to Hennig Die Fliegen material.

I also used Hennig to id the female Spilogona.

Best wishes, Nikita and Matej,
John

Thank you all for interesting information. For me, as an amateur, especially some simple hints are valuable. I am not sure if I once am able to use keys for Muscidae or Tachinidae, but when I retire... :)

Best regards
