For the third time following 2009 and 2010 butterflies native to Liechtenstein feature centrally on a definitive stamp. The “Butterflies – III” issue, again designed by Stefan Erne, depicts two more harbingers of spring, the Orange Tip and the Peacock. The “Peacock”, Inachis io (face value CHF 2.20) from the Nymphalidae family was the “Butterfly of the Year 2009”. Since because of global warming this butterfly now regularly forms a second generation in the late summer, it has been chosen to draw attention to the consequences of climate change. The conspicuous black, blue and yellow eye spots on its russet-coloured wings serve as effective protection for the Peacock against its natural enemies. When danger threatens, in a flash the butterfly spreads its wings to display their striking upper side, leading the predator to imagine itself confronted by a large creature proportional to the eye(spot)s.The Orange Tip Anthocharis cardamines (face value CHF 5.00), whose German name the “Aurora” Butterfly was inspired by the goddess of the dawn, can be observed in spring in large swarms in Liechtenstein’s valley landscape. Both males and females of this species of White have white wings, the outer half of the forewings being coloured orange only on the males. The irregular yellowish/dirty green and white speckled pattern on the underside of the hind wings is however common to both sexes. Like the first two “Butterflies” series this issue too is being produced as a self-adhesive stamp.
