• ]. The second strongest signal corresponds to the presence of crystalline α-Fe with a magnetic hyperfine field of 33.05 T and an isomer shift of 0.00 mm/s. The last easily distinguishable subspectrum characterized by a high magnetic hyperfine field of over 34 T is seen in the form of side slight “wings

The hexagonal shape of the ommatidia is clearly visible with each facet measuring about 25 µm across. The entire eye

The LUMO is located exactly at the flanks of the molecule appearing like the wings of a butterfly. Consequently, the molecule

Surfaces similar to our patterns are not uncommon in nature. Insects show a wide variety of ornamentations of their cuticle, their compound eyes and wings [10

The little air film, however, might primarily help to keep the wings dry. The upper side of the elytra is hierarchically structured by

• surface. Also the decreased air–water interface itself leads to a higher resistance against water pressure according to the model of Crisp and Thorpe [17]. The tiny, but stable, air film on the underside of the elytra seems to be more relevant to keep the wings dry rather than playing a role in the
