marbled and netted with green. Many of the species, especially 

 the males, have the front wings tipped with orange which gives 

 them the name. Most of the species are found in the far West, 

 only two are occasionally found in the East. 



The Flacate Orange-Tip. — This butterfly has the apex of the 

 front wings prolonged into a hook shaped point. Only the males 

 have the front wings tipped with orange. The caterpillar feeds on 

 cress, shepherd's purse and other crucifers. 



THE YELLOWS 



The Roadside Butterfly — This is the most common repre- 

 sentative that we have of the yellows, and it may be seen in the 



summer in great numbers flit- 

 ting above the flowers of our 

 roadsides, or settled for a social 

 drink about some mud puddle 

 in the road. Its caterpillar is 

 small, green in color, and feeds 

 on clover, vetch, lupine, etc. 

 It is so well concealed by color 

 that it is rarely found.

broad black band and the 

 dark spot in front of the middle of the front wing extends 

 up and down and is a mere line, looking like a closed eye. The 

 caterpillars feed upon cassia, clover and senna. The species is 

 common in the Southern States. 



The Dog's Head. — The wide black border on the front wing of 

 this butterfly outlines on the yellow a head that resembles that of a 

 duck quacking more than that of any dog. However, the picture 

 on the wing of the female is slightly like the profile of a poodle's 

 head. The black spot forms a large and startling eye. The cater- 

 pillar feeds upon false indigo and clover. This species is abundant 

 in the south western United States and Pacific Coast. Its wing 

 expanse is about two and one-half inches. 



The Little Sulphur. — This is a pocket edition of the roadside 

 butterfly, marked like it except that it has a dot instead of a spot
