Its fascinating how it blends perfectly with the environment. Unfortunately I took this image with the only lens that I had on me (28-105mm). However even though this image is nothing more than a record shot, I thought that I would still share to show the splendid world that we often take for granted. Here is a link to a website about insects found on Etna.
