Show WORLD OUTDOORS HOW convenient for human beings that they can grow into adulthood without the gradual stages of metamorphosis. So necessary nec-essary to insect development. We grow without effort. Insects with complete metamorphosis pass through four separate stages during dur-ing their life cycle egg to larva to pupa to adult. Some insects must laboriously shed their old skin as many as a half , dozen times. The skin or outer skeleton of the insect is hard and does not grow as he grows. Consequently, he must shed the skin, or molt the outside skeleton, if he is to grow. The crayfish has a tough outer shell and a strong set or pincers. In the warm days of spring and summer, the crayfish sheds this tough outer skin and becomes virtually vir-tually defenseless. Unless he is able to hide beneath some rock until his new skin hardens and his strength and agility returns, Mr. Crayfish is most likely to become be-come a tasty morsel for some fish, snake, raccoon or bird. "Soft Craws" as they are called by fishermen, are recognized by experts as top bait forsmallmouth bass and where craws are used you will often hear the expression, "If craws don't get 'em, they won't be had." Another outstanding bait, and one that is available for most of the year is the hellgramite, or "go-devil," which is the larva of the Dobson Fly. The "go-devil," which looks something like a caterpillar, is not so defenseless as the soft craw. The familiar leaf-eating caterpillar has two "antenna" on his head. The go-devil has strong pincers instead of antenna and with these pincers he can draw blood from the finger of an unwary fisherm an who thoughtlessly grabs him anywhere except by the strong "collar" directly behind the head. |
