SWALLOW-TAIL BUTTERFLY. 159 



This Papilio and the Papilio podalirius, are the 

 only two species of Swallow-tail Butterflies that have 

 yet been found in Britain. Both are very scarce ; 

 but the present less so than its congener. Harris says 

 it feeds on wild fennel and carrots. He mentions 

 that one he found, remained in the chrysalis state 

 from the 23d September, till the 15th May following ; 

 and another, that changed July 14th, produced a 

 butterfly on the 10th of August. He adds, that the 

 species was found in the meadows of Bristol and 

 Westram. 



This insect is common on the Continent of Europe.
