Hello, I'm new in the forum.
Well, I have a personal interest in identify everything is around my country house; In fact I try to emulate someone in Monegros (Zaragoza, Spain) who got an invertebrate list of more of 4500 invertebrate species of the same locality.
First I would like to ty to identify two apparently different Calliphora species. The pictures are not of a good quality, but may be someone could help (anyway, I have read all the messages with the term "Calliphora"); I don't have any special material but a simple digital camera, a magnifying glass and a scanner...
And sorry about my English...

Here is the second one
The fist one was bigger (12 mm), with black eyes and cheeks not very red.(24.12.2005)
This one was smaller (9 mm), with eyes and cheeks quite red.(23.11.2005)
All of them were found as dead at home in Can Grau, Beuda, Girona, Spain, UTM31TDG7477, 400 M.

Dear Rafael.
For identification of Calliphora species you need lateral vue of head and thorax with clearly visible colours.
Try to use this virtual key

From what I can see in your pics I would guess that they are both
C vicina, but if you can look at the actual specimens, magnified, and use the key as Nikita suggests, I would think you should be able to work it out for certain, even with dead flies.
I assume you have read Theo Zeegers comments to me in a previous thread about these two species. You may be interested to know that every single specimen I have checked since then has turned out to be
C vicina, as Theo predicted. The ones I am seeing vary considerably in size, certainly within the range of yours, sometimes even smaller. The difference in eye colour might just be discolouration over time after death?

la zona ?s treballada; es va publicar i trobe que els llistats d?esp?cies es poden descarregar per internet; seria per a tu una refer?ncia millor que el cat?leg de diptera, busca per la SEA, crec que ho vaig veure all?
(diptera species list in Monegros is publicated, try SEA web )
