Pupa (x 3): h, head; e, eye case; th, thorax; ant, antenna case; tc, tongue case; Ic, cases of front and middle legs; wc, wing cases; sp, spiracles: a, ahdomen; cr, cremaster. Butterflies and moths constitute the group Lepidoptera (or scaly-winged insects). Capture a few of the moths that are attracted to a light at night, and examine them, to discover wherein moths differ from butterflies. THE LIFE PROCESS IN INSECTS. I. Nutrition. — The food of insects is so various, that diverse organs are necessary for seizing and preparing it for digestion. The mouth parts normally present are (1) a labrum; (2) a pair of mandibles; (3) a pair of max- illse, each with three free appendages, — lacinia, galea, and palpus ; and (4) a labium, with its jointed palpi. Any of these parts may be specialized, modifled, or sup- pressed, according to the needs of the animal.
