Bright Glasswing. Lesser Banded Hoverfly, Syrphus vitripennis, Hortus Botanicus, Amsterdam, The Netherland

They're hard to distinguish, Syrphus ribesii and Syrpus vitripennis. But judging from the color of the third femur - dark or even black - this is Glasswing, Lesser Banded Hoverfly. He's basking in the bright Spring Sun in the Hortus Botancius which isn't only a labeled plant collection but also a veritable Insect Zoo, challengingly unlabeled, of course..
