Hemaris thysbe

≠The key differences

H. thysbe is very similar but has an olive-green thorax, a dark red-brown abdomen with yellowish patches, and pale (yellowish) legs; H. diffinis has black legs and a black stripe running from the eye along the side of the thorax.

Very similar and often confused; H. diffinis has black legs, a black band across the abdomen and a more yellow-and-black 'bumblebee' look, while H. thysbe has pale legs and an olive-green thorax with a burgundy abdominal band.
