The cabbage cat- erpillar moults sev- eral times before reaching full size, and at the final moult it seeks a se- cluded and dry spot, under the clapboard- ing or coping of a house, or under a board or leaf. It first fastens itself to the sheltering sup- port by a tuft of silk at the tail, and also makes a sling of silk around the waist. Then a remarkable thing takes place. The old caterpillar coat sphts and is cast off. But the insect no longer looks Uke a caterpillar. It is now a pointed, angular case, called a chrysalis.
