BUTTERFLIES OF THE VICINITY OF NEW YORK CITY 



4. Giant Swallowtail (Papilio cresphontes). 



This handsome Swallowtail Butterfly is one of the commonest in- 

 sects in the South, and is seen everywhere flitting about in the orange 

 groves. When first discovered, it was thought to be restricted to 

 the South, but within the last twenty years the butterfly has extended 

 its range very much, being now found as far north as Canada. In 

 the vicinity of New York it is not common. It is double-brooded; 

 the first brood appearing in June and the second in August. It 

 may be known by its large size and its deep black wings, with a row 

 of large, rounded, yellow spots running obliquely from the apex to 

 near the base. From about the middle of this row begins a row of 

 spots which runs to the hind angle. The hind wings have a rather 

 broad band across the base, and a series of large yellow spots running 

 from the apex to the inner angle. The under side is almost entirely 

 yellow. The caterpillar is dark brown with a white band on each side,
