32 The Council Ring is a good place to look closely at things around you. You might find. 33 .a . .a spider's web which looks like an artist's design. The spider spins this web of finest silk not for beauty but as a trap to capture small insects for food. The insects are held by sticky threads. Do you know how the spider keeps from getting stuck? The spider is another predator, for its food consists mainly of insects caught in the web. Not all the threads of the web are sticky and the spider can distinguish between the two. 34 Perhaps when you look closely you will find a long- legged green insect. The katydid will not live through the winter, but will lay eggs in the fall which will hatch in the spring. Katydids eat green leaves. Can you think of something which might catch and eat a katydid? The katydid is related to the grasshopper. Members of this family -hatch from eggs into a form similar to the adult but smaller and without wings. Several molts are needed to reach adult size. Some katydids are green; all have very long antennae and are found in trees and bushes. Each species of male katydid has a characteristic "song." 35 Some insects do live through the winter. The wooly bear caterpillar will hide beneath a log or piece of bark. Can you look closely and see something else that is alive in this picture? Hidden in a hole in the wood is an insect which will spend the winter as a ''pupa."~ A pupa is an intermediate stage in the develop- ment of many kinds of insects (egg--larva-- pupa--adult). Often a hard pupal case surrounds the insect affording protection. A cocoon and chrysalis are examples of this case, with the pupa inside. 22
