III. BUTTERFLIES AND MOTHS 



Material. Some caterpillars kept in the schoolroom until they undergo 

 their changes. Use green worms from cabbage plants, or red spiny cater- 

 pillars from hop vines, or smooth yellow and black caterpillars from milk- 

 weeds. Each of these will usually complete its changes within two or 

 three weeks. Other kinds of caterpillars may be used, but many of them 

 do not complete their changes until winter has passed. 



1. THE CATERPILLAR 







Observation. What is the size of the caterpillar 

 that you observed ? What is its shape ? What is 

 its color ? How many joints has its body ? Is its 

 body naked, or is it covered with spines or hairs? 



Notice two kinds of legs on the caterpillar. How 

 many legs are on the front end of its body ? What 

 is their shape ? How many legs are on the hinder 

 half of its body ? What is their shape ? 



Notice a caterpillar's jaws. Do they move side- 

 wise or up and down ? Does a caterpillar suck the 

 juices of leaves, or does it lap its food from the sur- 

 face,, or does it bite off its food? Does the caterpil- 

 lar eat the middle or the edge of the leaf ? 



Drawing. Draw a picture of a caterpillar. First, 

 in very light lines, draw a figure about the size and 

 shape of the caterpillar. Then, in heavy lines drawn 

 over the light ones, make the head and tail ends in
