"Yes, certainly; all butterflies lay eggs, from which proceed caterpillars, which generally destroy the plants on which they are hatched. When arrived at maturity, the caterpillar spins a cocoon of silk, more or less fine, in the centre of which it incloses itself. It is then called a chrysalis. In this cocoon the butterfly is formed, either white or black, yellow or green, and there it remains inactive and imprisoned, like a baby in swadding-clothes. In spring it perforates its silken prison, and soon makes its escape a splendid butterfly, subsisting upon the juices of the flowers obtained through its proboscis. Surely you were not ignorant of all these transformations?"
"I thought that they only took place in silk-worms."
"Well, now you are undeceived; all caterpillars and all butterflies are subject to them; but there are few caterpillars which spin so valuable a cocoon as the silk-worm. Moreover, some bury themselves in the earth; while others hide in the middle of a leaf, the edges of which they curl round so as to form a kind of bag, in which they are protected from the beaks of birds; again, some hollow out a shelter in the trunk of a tree, and line their abode with silk more or less fine. Thus, in every case, the chrysalis waits patiently for the time when it will change from a worm into a butterfly, painted with the richest colors."
The subject was really an inexhaustible one, so I deferred the rest of my explanations to another day. Besides, l'Encuerado was loudly calling for us.
