Pic taken Yesterday South coast UK bug body length about 11mm
According to my British Insects book it's Eupeodes nitens but another hover expert thinks it's Xanthogramma pedissequum. Any views ?
(I'm not an expert BTW). If it's any help- it's territorial flight was different to hoverflies I've watched as it also bounced up down by about 3cms continuously.
Thanks Brian V.
