This is the most common species in the vicinity of New Haven. 

 It is found on the salt marsh, along roadsides, and on dry, light 

 soil, especially in the bunch-grass, in the roots of which it is 

 said to deposit its eggs. Its song, which is very loud and much 

 resembles that of the harvest-fly, Cicada canicularis, is frequently 

 heard late in the afternoon and during the evening. New Haven,
