The eggs of Insects ex- hibit a wonderful variety of forms, sizes, colors and characteristic markings. A single scale Insect may lay thousands of eggs, while some plant-lice produce only one. Remarkable instinct is often shown by the mother Insect in placing her eggs where her young will find proper food. From their birth the young of some of the lowest or most generalized Insects closely resemble their parents, and they undergo no striking change during their life; hence are said to have no metamorphosis. In the case of grasshoppers, stink-bugs, dragon-flies, and many other Insects, the young at birth resemble their parents, but have no wings. As they grow, wings gradually develop and often changes in markings occur, until the adult stage is reached. The growth, however, is gradual, and no striking or complete change occurs, and these Insects are said to undergo an incomplete metamorphosis. The young Insects in all stages are called mymplis (Pig. 1138); thus Insects with an incom- ^3 1^^€ ^'^w^B m^M l^^iiU tomato worm. 1147.
