I took these Cicada's at a beach resort in Crete this summer, my father and I went to have a look around the grounds of a hotel behind Costa Beach where we spending some free time on a tour of the beach and Chania Town. Its quite unusual to see Cicada's this close, we mostly just hear the cacophony of "hissing" they make in the trees of tropical countries in the Summer months. They were all over the tree barks in the hotel grounds, apparently the male of the species has a tymbal underneath their main body that expands and contracts making the clicking sound they are famous for.
