Larval development. At the end of about three days of embryonic development, the embryo breaks the chorion and becomes a young larva. Dining the larval period the most striking feature is the enormous growth of the animal. The illustration on page 40 (Fig. 35) shows an egg, a relatively young larva, a fully grown larva and a pupa drawn to the same scale and, when it is realized that the growth from the youngest larva to the fully grown larva takes place in a few days, the rapidity of growth is astonishing. It should be pointed out that the development of all insects is not simi- lar. In the grasshopper, for example, a young insect hatches from the egg which resembles the adult in most respects. Such a development is known as incomplete metamorphosis. In the higher orders of insects, there hatches from the egg a larva unlike the adult and usually more or less worm-hke, which when fully fed undergoes a complete and relatively sudden change into the adult. This type of development is known as complete metamorphosis. The bee larva is an extremely simple organism, lacking legs, wings, anteimse apd eyes, and is unprotected by hairs or thick chitin. A longitudinal section through the larva (Fig. 52) shows that the largest organ is the stomach, as is necessary for excessive growth. Being protected from enemies and from adverse environmental conditions in the.
