Curious process is not, the metamorphosis of butterflies, as they go from having a form to another completely different in every way, as it changes their way of walking, small climbing legs, on the stem and leaves of plants, to long, slender legs that use very little to walk; from having a plump body and striking colors, to a dark and slender body; developing two sets of thin wings, with millions of micro scales that give him extraordinary colors and drawings; and from eating our plants in the garden with their small jaws, to a sucking mouthpiece that consists of a long trunk that is sometimes rolled up and used to suck the flowers, catching the pollen with its legs and contributing its grain of sand to the pollination of plants.

The drawing that I show to you next is elaborated with the technique of the chiaroscuro, in this opportunity the process consisted of an initial sketch, from which I darkened the lines that would represent the darkest spots of the caterpillar, to later fill them. Now the darkest tones are finished, work the medium tones and the shadows that take away the rigidity of the drawing and give it the particularity of volume and movement, to finish with the drawing, develop the shading of the vegetation and that's it.
