With the exception of the true Katydid this is our largest 
species. It frequents shrubbery and small trees, preferably 
in moist places, crawling 
slowly about and some- 
times flying leisurely from 
place to place, when its 
large tegmina and wings 
make it a conspicuous ob- 
ject. It reaches maturity 
by mid-August in New m 
England (June in Louisi- .^ 
ana) and probably can be ^ ^, , . j rr . jj ^ w i u
