In color and ornamentation this is one of the least variable of 
our Pygmy Locusts, resembling closely its surroundings in tint 
and texture, ranging from pale gray or ochre to a blackish slate 
color, either uniform or slightly mottled, and often with a pair 
of triangular dark patches on the shoulders. 
It prefers the immediate margin of lakes, ponds, and streams, 
where it delights to sun itself on projecting stones. When dis- 
turbed it flies freely, even for several yards at a 
time, and often alights on the water, where it 
swims well. 
In distribution it is somewhat southern and quite 
local. It has been recorded from various points in 
all parts of Connecticut, from the vicinity of Boston 
(Scudder Coll.), and I have taken it on a stony 
stream-bed at Alstead, N. H. Specimens found on 
the sandy mud of lake shores at Canaan and 
Thompson, Ct., were yellowish gray; others from 
a stream-side at New Haven, strewn with frag- 
ments of blackened wood, were so dark as to 
seem almost black, in both cases so closely match- 
ing the background as to be practically invisible. 
Adults have been recorded from July 13 to 
August 29, and young in several stages, even very small, were 
common at New Haven on the latter date. Its exact life history, 
and the stages in which it passes the winter, are unknown.
