68 INSECTA 



(b) For butterflies and other insects with large and 

 beautiful wings, use separate papers as follows: 

 Let the wings of the butterfly be folded over its 

 back. Lay it on its side on a rectangular piece of 

 paper. Fold the paper down over the butterfly, 

 forming a triangle, and turn the margins over to 

 keep the paper closed. 

 (4) Breeding Jar. Prepare several breeding jars for rear- 

 ing insects from the eggs or larvse. Place a couple 

 of inches of sand or soil in the bottom of a quart 

 fruit-jar, cover the jar with a piece of cheese-cloth, 

 securing it in place by a small rubber band. 

 When insect eggs or larvse are found, place them, 

 together with a portion of the plant on which they 

 are found, in the jar. Moisten the sand, but do 

 not make it too wet, and renew the food every day. 

 If the plant food is too far away, or if it will be less 

 trouble, place a small bottle of water in the bottom 

 of the breeding jar, and keep a branch of the food- 

 plant in it. Renew this as needed, for caterpillars 

 are greedy, and you will need to keep a good supply 

 of food for them. 

 2. Field Trip. 

 (1) Habitat. 



(a) Look in the grass and wxeds, under stones and 



boards and logs, and in old rotten stumps, on the 

 bark of trees, in galls and rolled-up leaves, and 

 especially upon any plants having leaves full of 

 holes or with ragged edges. 



(b) Look on the surface of the water of a pond or slow 



stream. Look in the mud along the edge, or 

 carry som.e of the muddy water back in a breed- 

 ing jar and let it stand for a few days. Examine 

 to see if it contains any insect life. 



(c) Look flying about in the air. 



(d) What three kinds of habitats do you find occupied 



by insects? Why do you find certain kinds of 

 insects in one place, and certain others in different 

 kinds of habitats?
