Hi

I found my first piophilids this week in G?is (1.4). They have around 4 mm -5 mm length.
These were found on corpse of sheep in advanced decomposition.

Edit: not a piophilid.. :(


EDIT Title changed from "Lonchaeidae and Piophilidae" to "Lauxaniidae - Calliopum sp. (1st) and Piophilidae - Stearibia nigriceps (2nd, 3rd)"

I'm affraid, not yet, Jorge.
There are a hell lot of carrion visitors, I think this one is Lonchaeidae.

hmm.. i must continue searching for them. :) Also I thought in Lonchaeidae... but I never saw a Lonchaeid (the other lonchaeids never flight as I saw this Tuesady) flying like this fly.

Jorge, on second photo - Piophilidae, but I think that pinned fly is not Piophilidae.

aha. So I really SPOTTED Piophilidae in the same corpse. I will take in next weekend photos of possible piophilids I caught. :)

Hi Jorge,

The specimen on your first foto doesn't belong to the family Lonchaeidae. The colour of the halters is all wrong.

Jan, if it is not Lonchaeidae (indeed it was my first thought before the Piophilidae...) what this could be? Milichiidae is not, by sure. This fly has a very dark green metallic colour. And the parafacialia and gena is even darker.

It could be a Calliopum or something like this...

Calliopum has striped eyes. This fly doesn't have... :(

If it isn't Lonchaeidae, than may be all images are Piophilidae?

Looks to be a Parapiophila sp. Guess, you are lucky as there is a few or no piophilids recorded from Iberian Peninsula.

Ask Andrei Ozerov, he is a real expert on that family.

Thanks Nikita, Jan, St?phane and Valery. I will contact Andrey Ozerov. :D

How easy is to make mistakes in these flies. :) Next weekend I will try to take more photos so we can reach the genus, at least,

I thought something was off when I looked yesterday but now I have found it. This frontal picture is NOT of the first specimen given in this thread. The head picture indeed shows a piophilid but notice the absence of metallic shine on the specimen and the absence of orbital setae. Both are present in the first picture of the thread. It still seems likely to me that that picture is of a Calliopum.

Stearibia nigriceps (Meigen) is present on second and third fotos.
My colleague A.Shatalkin examined first foto and agree with P.Beuk that it is Calliopum.

You are right Paul. But I'm surprised to know that the fly is really a Calliopum. :) I will check my specimen in Friday.

Thanks Andrey. I will look more for more corpses... maybe crabs, too. :D

Thank you Jan, I didn't know this useful information :o

Nice to know that the colour of halteres can discard lonchaeids in the cases it appears apparently one of it. :)

However, there are other families with species that have black halteres, for example in the Agromyzidae.
