BUTTERFLIES OF THE VICINITY OF NEW YORK CITY 



Very rare in this vicinity. It is closely allied to T. calanus, but 

 differs in the position and number of white lines on the under side. 

 The butterfly appears to be local, and is rarely found away from 

 thickets. It flies early in July, and is rarely found on the wing after 

 the first of August. The eggs are laid in July and remain unhatched 

 until spring. The caterpillar feeds on oak, holly, thorn, plum and 

 apple. 



49. Hoary Hair-Streak (Thecla irus). 



Rather common locally in this neighborhood, especially in pine 

 woods and open places near where huckleberries grow. The cater- 

 pillar is said to feed on these plants. It lives on the wild plum also. 

 The butterfly appears during the latter part of April, and is on the 

 wing until about June. 



50. Coral Hair-Streak {Thecla titus), 



The butterfly frequents flowers in open sunny places near thickets 

 and woods. It is found in July and early in August, and is single- 

 brooded. In this vicinity it is considered rare, but occasionally it has 

 been found in considerable numbers. Its color is sepia-brown, with 

 a row of coral-red spots along the outer border on the under sides of 

 the hind wings. The caterpillar lives on plum and wild cherry.
