HOW TO KNOW THE BUTTERFLIES 



The sleepy yellow loves society, and flocks 

 over the clover fields and upon forest-bordered 

 meadows ; when gathered in numbers on the 

 moist earth they look like a patch of brilliant 

 sunlight. It is a southern species extending 

 from the Atlantic to the Pacific. Sometimes it 

 appears as far north as New York, Ontario, and 

 Wisconsin. 



The caterpillars eat the tips of the cassia leaves 

 at first. There are three distinct broods and 

 probably more, as Mr. Edwards found in Septem- 

 ber in West Virginia a branch of senna on which 

 was every stage of this butterfly, from the egg to 

 the newly emerged adult. 



Thou spark of life, that wavest wings of gold ! 



Thou songless wanderer 'mid the songful birds, 

 With nature's secrets in thy tints unrolled 



Through gorgeous cipher, past the reach of words, 

 Yet dear to every child 

 In glad pursuit beguiled, 

 Living his unspoiled days 'mid flowers and flocks and 

 herds. Higginson. 



The Little Sulphur

Although this species is larger than the dainty sulphur, it is 

 considerably below the average size of our yellows, the larger
