If you count also the not-quite-young Appreciation, we share three things: We grew up without a cell phone, read Newspapers on paper, and remind us that there used to be more butterflies.
As a child, I spent every year in the summer holidays in Ticino. I remember the evenings, as hundreds of these black butterflies with white dots on the river fluttered. Even today, I regularly go to the maggia valley, it is only now that I noticed, though, that I encounter them only rarely, these clumsy-flying Butterflies.
feast for the eyes for YB-Fans
When the type is the white-spot Burnet. The moth has a wing span of up to four centimeters. Upon closer inspection, the black wings Shine bluish and white dots, never the same number and of different sizes. Just for a YB-Fan also of the yellow Ring is a feast of the abdomen to the eye. The Butterfly is from the South, but also North of the Alps.
Especially just the appearance of the moth is not, particularly is that he mimics a different species of butterfly: the Variable Burnet (Zygaena ephialtes), which is for birds toxic. Therefore, the predators can also often of non-toxic white stain-Aries Chen. Mimicry is called this phenomenon. Even the scientists who gave to the Moth his name, he crawled to the glue: in fact, it belongs in the family of bears spinner, not to that of the RAM cells.
The agriculture, we are all
What is deceptive, is our memory. The butterflies are really less – together with all the other insects. Thanks to new scientific studies, we know that the Situation is, unfortunately, dramatic. It is assumed that the number of insects has decreased in the last thirty years, up to 80 percent. One of the main reasons is agriculture.
however, We should not blame the hard bastard ends farmers on the 50’852 Operated in Switzerland in the shoes. The agriculture we all are. And we all can do something against the threatening decline of insects, as consumers, voting citizens, or about a hobby gardener.
