Hyles gallii, also known as the bedstraw hawk-moth, is a moth of the family Sphingidae. The species was first described by S. A. von Rottemburg in 1775 and is found in North America, in Europe to the Arctic Circle, in Central Asia, and in Japan. This image shows a late-stage H. gallii caterpillar in Keila, Estonia. Caterpillars of the species can reach a length of 70 to 80 millimetres (2.8 to 3.1 in), with variable colouring. One type is olive green with cream spots and a reddish-brown head, while another is almost entirely black.Photograph credit: Ivar Leidus
