 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.. Sad


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

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

 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... Sad

 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. Grin

How easy is to make mistakes in these flies. Smile 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. Smile I will check my specimen in Friday.

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

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

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

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
