The striped tree cricket is the most common member of its kind 

 in Indiana. In August and September, nearly every stalk of golden- 

 rod and wild sunflower along roadsides, in open fields or in fence 

 corners, will have from one to a half dozen of these insects upon its 

 flowers or branches. It is also especially abundant upon the tall 

 weeds and bushes along the borders of lakes and ponds, and in 

 sloughs and damp ravines. 



The note of fascia lus is a shrill continuous wlii-r-r-r-r which is 

 kept up for several minutes with the intervals of irregular length.
