THE COMMON SKIPPERS 



This insect was long known under the specific 

 named hur-on, which probably suggested the 

 common name sachem. The species is distrib- 

 uted over the eastern two thirds of the United 

 States. In the South the larva feeds on Bermuda 

 grass, and makes a retreat by fastening together 

 leaves.

 The two sexes of this species differ greatly in appearance 

 when seen from above. In the male the upper surface of the 

 wings is largely yellow, with a brand, and with a dark 

 brown outer border; in the female the wings are almost en- 

 tirely dark brown, with a transverse row of spots beyond the 

 middle of the fore wings. The most distinctive feature of 

 this species is the color of the lower surface of the hind wings, 

 which is similar in the two sexes, and is a greenish yellow 

 spotted with distinct dark brown spots. Expanse of wings 

 one and one-tenth to one and one-half inches. 



This skipper has been found along the sea- 

 board from Connecticut to Mexico.
