Your letter to the bugman: Hello BugMan! I wanted to show you this variation in color of the (perhaps) Barbary Spurge? Hornworm.(OR tell me the exact ID; I see some with two dots!) We found these while riding camels in Erg Chebbi sand dunes on the vegetation shown. We gently tickled one and put him on a leaf to better photograph. Then we put him back on leaves. There were LOTS of them! They can make their way quite fast over the sand when looking for another bush! I took the photos on September 26, 2019. Thank you!
How you want your letter signed: Cynthia S.
This hornworm is definitely from the genus Hyles, but we cannot be certain of the species. It does look most to us like the Barberry Spurge Hawkmoth caterpillar pictured on Sphingidae of the Western Palaearctic.
