The Council Ring is a good place to look closely 
at things around you. You might find.

.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.

 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."

 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.
