Hi

* locality - Silgueiros - Viseu - PORTUGAL
* date - 2007.08.21
* size - 7 mm (medium fly)
* habitat - open land
* substrate - on stone (sandy hard soils)


I think this is Craticulina sp.


EDIT---> Title changed from "Sarcophagidae - Miltogramminae - Craticulina sp. ?" to "Sarcophagidae - Miltogramminae - Miltogramma cf. punctatum" and then to "Sarcophagidae - Miltogramminae - Miltogramma cf. punctata" SEE HERE the reason --> http://www.dipter...ad_id=8338

Why ?

Why not Miltogramma ?

Theo

---

it was a supposition. I don?t know well (yet) the Miltogramminae. :)

I will upload more photos later. (other views)


For now (and other subject): Theo, do you know which is the biggest tabanid we have in Iberian Peninsula? (known so far.) And what about the size..

Thanks!

---

frontal view. Very nice gena! :)

---

other..

---

It's Miltogramma punctatum or allied,
look at the peculiar hairs on first tarsus !

Liekele might be more specific (I'm not into Iberian Miltogramminae)


Theo

thanks, Theo.

You forgot this question:

"For now (and other subject): Theo, do you know which is the biggest tabanid we have in Iberian Peninsula? (known so far.) And what about the size.."

Tabanus sudeticus is the biggest in Europe, I guess you have it in the Pyrenees (no, I know for sure)..
Length up to 25 mm.

And T. barbarus in Andalucia is magnificant.
T. rectus can get really large as well

Both up to 24 mm.

All claims of longer horseflies by estimation, not measurement, are unreliable.
A horsefly of 25 mm. is estimated to be 50 mm. in the field !

(however, 50 mm. is more than a female Scolia flavifrons, you know this species).


Why ?

Theo

---

Because a friend of mine caught a 3 cm tabanid. He confirmed that it is very similar to Tabanus sudeticus. Ican be another species though...
He caught it in Sagres - PORTUGAL.

I know many Scolia, and Megascolia (this is really impressive for a wasp - I have one with 4 cm lenght!!!! It is MEGA :D)

---

Let's see photos :D

---

Measure it when dried, it's not larger than 27 mm

Wanna bet ?


Theo

---

Crex, photos will be available just when my friend gives to me the fly..

Theo, the dried fly measures 25 mm. :) You can play in EUROMILLION. :D

My friend reported that he saw big pustules on a cow... and he said that the tabanid got out from those pustules :S I think this is not possible due the fact that larvae tabanids evolve in water... So what could it be? Any clue?

He reports too that he saw bigger flies (tabanids) than the specimen he has.

I think our tabanids are much bigger than the nearctic ones. :D (sorry, Tony) :D

---

Personally, I would not put too much faith in your friend's abilities at identifying tabanids or estimating size:)

---

:D lol my friend knows what is really tabanid or what is not! :P
and he knows use a ruler. :D

---

Very interesting the pustules or warbles as they are called.
This is clearly the larvae of Hypoderma, either bovis or lineatum.
Collect !!!!

Theo

---

I suppose that Hypodermatidae was before in Oestridae family? Is it right?

My friend told that those flies appears ONLY in a short days (2 weeks to 3 weeks) and always in the hottest weather.


I don't have any cows near. :( :(

---

Hypodermatidae ? I wrote Hypoderma.

Hypodermatidae are still considered to be a subfamily only (Hypodermatinae) in the OEstridae. But various authors have various
opinions on the phylogeny of OEstridae s.l.

Theo

---

Theo, thanks! I know.. :) It was a question because I see that some authors think the Hypodermatidae as family. See here from Siberian Zoological Museum (this is another museum I'd like to visit..)

>> Great news for you: I found two spectacular tachinids. One is all golden, and the other one has some unusual colourful eyes! :S

---

I've been in Novosibirsk, actually they have more species than listed, like the magnificant Portshinskyia !

Anyway, different authors treat the (sub)family-status of Hypodermatid/nae differently.
Currently there seems to be consensus to unite all bot/warble flies into 1 family: Oestridae. (even Gastrophilinae included).

Theo

---

And there is NO virtually any info in the net about Portshinskyia . :D
It is extremely rare when we googling it doesn?t appear at all any info about the word typed. :P Even in the scholar.google.com or yahoo.com
It must be a treasure! :)

---

up. :)

---

The bristles on the tarsus of forleg are partly like Miltogramma punctata, but partly not.

I do not know any european species with such arrangement of bristles on male tarsus.

I need the specimen for positive identification.

Liekele

---

punctatum or punctata?

I will try to take other photos (in other angles) to the tarsus of foreleg very soon (not today).

Thank you, Liekele and Theo.
