BUTTERFLIES OF THE VICINITY OF NEW YORK CITY 
45. Snout Butterfly (Libythea bachmant). 
This species may be recognized easily by its long beak-like palpi, 
hence the name Snout Butterfly. It is somewhat rare here, though 
it sometimes appears in numbers. It flies during May, July, August 
and early September, and is two- or three-brooded. The caterpillar 
feeds on hackberry (Celtis). 
Family LYCAENID. 
These are small butterflies, with or without fine, short, hair- 
like tails on the hind wings. They have six legs adapted for 
walking. They are commonly called Blues and Hair-Streaks. 
The caterpillars usually live in flower-heads of various kinds of 
plants, feeding on the tender parts of the leaves only when com- 
pelled to do so. They are more or less oblong oval or oval, with 
the head retractile into the first segment, and have a ridge along 
the back. The chrysalids are short, fastened at the anal ex- 
tremity, and have a loop of silk around the body, much as do the 
Papilionide. They may be separated as follows:
