Cyclopedia of American horticulture, comprising suggestions for cultivation of horticultural plants, descriptions of the species of fruits, vegetables, flowers, and ornamental plants sold in the United States and Canada, together with geographical and biographical sketches. Gardening. 1148. Imago of a tent-caterpillar. plete metamorphosis pass through three different forms during their life: an egg, the young or ni/mph stage, and the adult. From the eggs of butterflies, moths, flies, beetles, bees and some other Insects, there hatches a worm-like creature, much unlike the parent Insect. It is called a larva (Fig. 1139); the larvfe of butterflies and inoths are often called caterpillars (Fig. 1140); maggots are the larv£6 of flies (Fig. 1141); and the term grub is applied to the larvie of beetles and bees (Fig. 1142). When these larvae get their full growth, some of them go into the ground, where they form an earthen cell, while others proceed to spin around themselves a silken home or cocoon (Figs. 1143, 1144, 1145). In these retreats the larvse change to a quiescent or lifeless-appearing crea- ture which has little resemblance to either the larva or the parent Insect. It is called a piipa (Fig. 1146). The pupse of butterflies are often called chrysalids. Flies change to pupje in the hardened skin of the maggot. Some those of mos- quitoes, are very active. Wonderful changes take place within the skin of the pu- pa. Nearly all the larval tis- sues break down and the Insect is practically made over, from a crawling larva to a beautiful, flying adult Insect. When the adult is fully formed, it breaks its pupal shroud and emerges to spend a comparatively brief ex- istence as a winged creature. Such Insects are said to undergo a complete metamorphosis, and pass through four strikingly different stages during their life: the egg, the worm-like larva, the quiescent pupa, and the adult Insect. Such remarkable changes or transforma- tions make the story of an In
