Hi guys, My daughter Rosie and son Sam saw these moths on our door today…initially we thought they were leaves. We have tried to find a similar image on your site, and although it looks a little like a Pandora Sphinx moth we are not sure. This photo is from Duillier in Switzerland. We hope you can help with the ID. Thanks
The Pandora Sphinx does not range into Europe. These mating Sphinxes are Mimas tiliae commonly called Lime Hawk-moths. More information and images can be found on Moths and Butterflies of Europe and North Africa and the UK Moths page. Lime refers to a favored larval food plant, the Linden Tree which is commonly called a Lime Tree.
