Thread subject: Diptera.info :: Chrysotoxum cautum? --> Chrysotoxum cf. verralli

Pictures are not large enough to measure antenna segments (in Ch. cautum the 3rd segment should be as large as other two segments together - it does not seem to be the case of your picture), however, my impression is Chrysotoxum verralli (yellow strips on tergites are triangular).
Ch. cautum's abdomen has a different pattern.
