Your letter to the bugman: Hello.I have been trying to identify this moth. But I do not know if it is Hemaris fuciformis or H.thysbe. Which one have I photographed? And what is the difference between both species?
Thank you. Isabel.

We believe this is a Broad Bordered Bee Hawkmoth, Hemaris fuciformis, and not Hemaris thysbe, a new world species. It is pictured on Sphingidae of the Western Palaearctic and on Insecta.pro where it states: “It flies from late May to early July.”
