As the author points out, the presence of butterflies is one of the most trustworthy indicators of the health of our environment. However, it is becoming harder to find species that for centuries were common and even abundant.
A less encouraging picture ever in the prevailing problems as the greenhouse effect, destruction of the ozone layer, increased forest fires, climate change ... which has prompted the concern of scientists and nature lovers and of all stakeholders in the conservation of wildlife.
According to Pedro Velasco, scientific advisor and photographer of nature, this unique publication on the Iberian butterflies "is intended for all audiences", and it includes hundreds of photographs and thorough descriptions of these insects, from their habitat and flight dates to their customs and location in mountains, moors, plains, river banks and Spanish forests.
Born minded informative, this book not only serve as mere consultation or memory of what once existed but for future generations understand and appreciate this part of the wilderness we have an obligation to preserve and appreciate and fortunately still persists in some parts of our country.
Its content is also a line of environmental conservation with a clear purpose: to teach the reader to recognize, observe, and above all protect the butterflies.
