The eyes are more or less pubescent and are contiguous (contacting each other medially) in males and widely separated in females.

The antennae are long and erect, inserted on the frontal angle, with the first two segments nearly equal, and the third one (flagellum) is three to six times longer than the previous ones.

The wings have the median transverse vein located before the middle of the discal cell.

[4] There are many Chrysotoxum taxonomy concerns yet to be resolved due to the few morphological features available for species characterisation.

Characters frequently used: the color of legs, the overall size, the connections between the various abdominal stripes and spots have been found to vary considerably within a species Differences in male terminalia, often of great diagnostic value in other genera are, so far, unhelpful among the majority of Chrysotoxum species.
