Note e — BOOK IX.

The motive Parts, and Motion of Caterpillars, are useful, not only to their Progression and Conveyance from Place to Place; but also their more certain, easy and commodious gathering of Food. For having Feet before and behind, they are not only enabled to go by a kind of Steps made by their fore and hind Parts; but also to climb up Vegetables, and to reach from their Boughs and Stalks for Food at a Distance; for which Services, their Feet are very nicely made both before and behind. Behind, they have broad Palms for sticking too, and these beset almost round with small sharp Nails, to hold and grasp what they are upon: Before, their Feet are sharp and hook’d, to draw Leaves, &c. to them, and to hold the fore-part of the Body, whilst the hinder-parts are brought up thereto. But nothing is more remarkable in these Reptiles, than that these Parts and Morton are only temporary, and incomparably adapted only to their present Nympha-State; whereas in their Aurelia-State, they have neither Feet nor Motion, only a little in their hinder parts: And in their Mature-State, they have the Parts and Motion of a flying Insect, made for Flight.
