THE wings of the Cerulean Butterfly are of a 

 deep azure blue, as also the body ; the under wings 

 have a very broad band of dull crimson at their lower 

 margin, which reaches nearly to their centre ; this 

 band is spotted with circular and triangular black 

 dots ; the whole posterior margins of both wings i 

 surrounded by a white edge. 



The female differs considerably from the male, the 

 upper side being of a dark brown colour 

 P The under side of the wings are handsomely 

 bordered with eye-like spots ; the other parts of the 

 wings are of an ash colour, besprinkled all over witl 

 small ocellated spots, or circles. 



This butterfly emerges from its chrysalis about he 

 beginning of June. It is found in several parts 

 Britain, but not in great abundance.
