Hi Imre, Duke, Brian and Wojtek,

Thank you for you comments ;-)

By the way: I can show you several anaglyphs from this very strange and ugly Insect. The fact was, that in my garden we had a lot of them each hot summer.

The adult insect, sometimes called an imago, is usually 2 to 5 cm (1 to 2 inches) long, although some tropical species can reach 15 cm (6"), e.g. Pomponia imperatoria from Malaysia. Cicadas have prominent eyes set wide apart on the sides of the head, short antennae protruding between or in front of the eyes, and membranous front wings. Desert cicadas are also among the few insects known to cool themselves by sweating, while many other cicadas can voluntarily raise their body temperatures as much as 22 °C above ambient temperature.

Take a look at the attached makro than you can see a really strange face!

Stay cool!
