This specimen was seen last morning eating on Elaeoselinum foetidum flowers, North of Huelva province in Andalusia, 450 meter above sea level. I have been watching the Syrphidae gallery and Doros is similar but I think it is another species, help.
Theo said that looks like Xanthogramma emarginatum? and I have upload the photos here in Syrphidae forum following his advice.
