HOW TO KNOW THE BUTTERFLIES 



the hind pair. The bronze copper is a rare in- 

 sect although it occurs from the Connecticut Val- 

 ley westward to Nebraska. Perhaps because it 

 is a giant of its kind it is more unwieldy in flight 

 than are its smaller relatives. It is fond of gold- 

 enrod, and finds the flowers of the Canada thistle 

 an attractive lounging-place. It frequents damp 

 places in meadows and may be found here and 

 there in salt marshes along the coast. It is dou- 

 ble-brooded, and winters as an egg. 



The butterflies yellow, 



As caught in an eddy 

 Of air's silent ocean, 



Sink, wander and steady 

 O'er the goat's-beard and asters, 



Like souls of dead flowers, 

 With aimless emotion 

 Still lingering unready 



To leave their old bowers.

 The wings above are brown in the male, with a strong re- 

 flection, in the female they are grayish brown. Both wings 

 are more or less spotted with black, and on the hind wings 

 there is a sinuous submarginal orange line, beginning at the 

 anal angle and fading out near the middle of the outer margin.
