locality has ever appeared, and no specimens have been seen 
since. It is, however, a species of wide distribution and powerful 
flight and its presence in Connecticut may be expected at any 
time. It ranges over the eastern part of the United States, the 
West Indies, and a large part of South America. 
Its flight is extended, swift, somewhat jerky, and rustling, and 
it perches indifferently on all sorts of vegetation from tall grasses 
and weeds to trees, rarely alighting on the ground. Rank growths 
of grass, weedy. jungles, shrubby pastures, and stubble-fields are 
its usual haunts, though it may be met with almost anywhere. 
In the southern States adults occur throughout the year, but 
are said to be more plentiful in autumn. Its life history varies 
much with the latitude, and irregularities are probably largely 
due also to variations in time and place of oviposition and rate 
of development.
