 LYC^NINJE. 



THECLA, Fabricius. 



This large genus is represented in Indiana, so far as known, by ten 

 species, but one of which may be said to be common. All are compara- 

 tively small in size, of a blue, smoky brown or black color, and have 

 wings of a delicate texture. The habits of all are essentially the same. 

 They mostly pass the winter in the pupa stage, and the imagoes are to be 

 found from May 1 5 until frost. They are seldom seen except along fence 

 rows and the borders of woods and thickets, where they flit rapidly to and 

 fro with a restless, jerking flight, pausing every few moments on leaf of 

 brier or shrub to bask in the sunlight, and then as suddenly starting on- 

 ward again.
