Welcome! Nice pictures, its a male Chrysura, either trimaculata or a species close to it - I'm not sure if there are more species similar to it in the east
Russia, Kirov region. 19.04.2014. It is possible to determine? Regards Vladimir. https://img-fotki.yandex.ru/get/9164/37421374.1ce/0_a9ee6_de53b6e4_L.jpg https://img-fotki.yandex.ru/get/9094/37421374.11d/0_8ca9c_43fd7cb1_L.jpg https://img-fotki.yandex.ru/get/9315/37421374.11d/0_8ca9b_53748d3a_L.jpg
I'm quite sure that it's a female of Chrysura varicornis, which is very common everywhere in the Iberian peninsula. It also has a similar punctuation of the abdomen.
Chrysuratrimaculata maybe? The fine punctation on tergite 1, triangularly raised metanotum and the date fits, but I'm not sure, could be more species with these characters in the Iberian peninsula
... + some other species in south of Europe) : metanotum +/- angulate posteriorly. (view in profile). hirsuta : black setae on metasoma, radians & trimaculata white setae)
yesterday I visited one of my favorite locations but dark clouds appeared and I could see only one C. trimaculata visiting one of these Euphorbiaceae. It's from the "golden edition" probably, because it's been very dry the last weeks.
