Coelonia solani is a moth of the family Sphingidae.

It is known from Mauritius, Réunion (formerly known as Île Bourbon), Madagascar and the Comoro Islands.

[2] It is a pollinator of some species of baobab in Madagascar, including Adansonia za.

[3] It is notable for having an extremely long proboscis (up to 19 cm long), approaching that of another more famous Malagasy sphinx moth, ie, Xanthopan morganii praedicta, which has a proboscis length of over 20 cm[4][5]
