HOW TO KNOW THE BUTTERFLIES 



waste places where she has at hand water-power 

 and sunshine-power to help her manufacture life 

 and color. Above such lands neglected by man, 

 the variegated fritillary hovers on golden red wings 

 or rests basking in the sun on the sands of drought- 

 wasted streams. It is a true recluse in habits, for 

 at the sound of an approaching footstep it rises in 

 the air and executes some acrobatic feats in flight 

 that the untrained eye is quite unable to follow 

 and then suddenly disappears entirely. Its color 

 has more of sunshine than is on the wings of 

 preceding species. Its caterpillar feeds stealthily 

 by night on the mysterious passion-flower. The 

 rapid flight of the butterfly is equaled relatively 

 by the rapidity which characterizes the traveling 

 of the caterpillar. 



The species is apparently triple-brooded in 

 some localities, and occurs throughout the United 

 States east of the Rocky Mountains, but is very 

 rare in the northern half of this rep-ion.

 oring of the two sexes. In the male the basal three-fifths of 

 the upper surface of each wing is dark velvety brown, the
