 The caterpillar is green, has red feet, and n yellow hood 

 over its head, and lives on several species of the cinnamon 

 tribe (laurinece). 



The POLYDAMAS (Papilio Polydamas) was so named by 

 Linnaeus, after the Trojan prince Polydamas, son-in-law of 

 the king Priam, and on account of the red spots was class 

 ed among the &quot;Trojan knights.&quot; It has wings of a dark

 middle by a yellow stripe, while the under side of the hind 

 wings is of a dark -brown color, with red dots on the mar

 has a light-brown body, with red lines and yellow spots, 

 and lives principally on birth -wort (Aristolochia serpenta* 

 rid). It is found in the South, from Georgia down to South 

 America.
