THE BUTTERFLY. 13 



Consult French's "Butterflies of the Eastern United 

 States," for finding the names of butterflies. 



DEVELOPMENT OF THE CABBAGE BUTTERFLY. 



The cabbage butterfly is small, yellowish beneath, paler 

 above, with black tips to the anterior wings. The male 

 has one round, black spot only on each upper wing, while 

 the female has two, and sometimes three. 



1. Open the abdomen and look for eggs. They are yel- 

 low, oval bodies ribbed lengthwise, with cross mark- 

 ings on the ridges, resembling stunted ears of yellow 

 corn. Look also for these eggs on cabbage leaves, or 

 where these butterflies are seen hovering. Watch the 

 butterflies closely as they light on the cabbage leaves, 

 to see the egg deposited on the leaf ; on which side of 

 the leaf are the eggs usually laid? How are they 

 fastened to the leaf? Make a drawing of the egg as 

 found attached to the leaf. 



2. Get a chalk box with a sliding cover; substitute a 

 glass cover a little longer than the box. Cut windows 

 in the sides of the box and fasten wire gauze over 

 them. Keep the box on end, so that the door will keep 

 closed, yet may be easily opened. Put into this box 

 a cabbage leaf with eggs on it ; examine several times 

 a day. What becomes of the egg ? In another box, 

 similarly arranged, put some large cabbage worms ; 

 give them fresh leaves every day, and keep the box 

 in a light, well-ventilated room. Watch closely, and 

 keep record of the date of the beginning of the ex- 

 periment, and note the date of any change ; describe 

 carefully all actions and changes in the worms. 

 Make careful drawings of each stage of growth :
