For interesting accounts of the life-history and habits of this insect 

 the reader is referred to McNeill's " List of the Orthoptera of Illinois," in 

 Psyche, VI., i89[, p. 5, and to Blatchley's " Orthoptera of Indiana," p. 436. 



Long-winged females of abbreviatus are common in Ontario, though 

 far less so than the short- winged individuals. On Aug. 26, 1901, I found 

 considerable numbers of them floating on Lake Huron, off the shore of 

 the Bruce Peninsula. I have never seen a long-winged male.

I have often found mymphs of this species in early spring under logs 

 and rubbish, where they' have passed the winter. The chirp of the adult 

 is first heard about the third week in May, the last toward the end of 

 July. They are most numerous about midsummer, when the fields and 

 pastures resound with their song. They are very difficult to obtain, 

 however, for they are not gregarious like G. abbreviatus, but usually 

 occur in pairs hidden in the rubbish under some thick tuft of grass or 

 weeds, or under the edge of a stone. It requires the utmost care and 

 patience to trace the song to its source, but if this is done successfully, 

 one is often rewarded by finding the female as well as the male. 



They are found everywhere in open woods and pastures, and are 

 most abundant on sandy soil. 



Blatchley says of this species in Indiana, that " the young hatch in 

 July and August, and after the second or third moult form their winter 

 abiding places, while the adults perish with the coming of the hoarfrost."
