Hi,
On 20 July 2014 I saw this Tephritid couple on Centaurea jacea in southwestern Brandenburg. It puzzles me because of the yellowish-hyaline wings combined with black spots on the tergites. The thorax pattern fits Terellia colon, however, and this species seems to be quite variable. So am I on the right track? Thanks in advance for any explanations!
