Cephonodes trochilus is a moth of the family Sphingidae.

It is very similar to Cephonodes tamsi, but distinguishable by the brownish rather than reddish upperside of the abdomen.

The upperside of the head, thorax and wing bases are unicolorous green.

The underside of the thorax and abdomen are uniform orange-yellow, the anal tuft yellow and the tip orange-brown, laterally partly black.

The larvae feed on Rubia and Galium species.
