Note 5 — Chapter I · THE PINE PROCESSIONARY: THE EGGS AND THE HATCHING
Alexander Teixeira de Mattos translation
The puny creatures measure a millimetre5 at most in length. Devoid as yet of the bright red that will soon be their adornment, they are pale-yellow, bristling with hairs, some shortish and black, others rather longer and white. The head, of a glossy black, is big in proportion. Its diameter is twice that of the body. This exaggerated size of the head implies a corresponding strength of jaw, capable of attacking tough food from the start. A huge head, stoutly clad in horn, is the predominant feature of the budding caterpillar.
