One had previously roosted every night for a week or 
more on the inside of the window. After this event it 
did so no more; and, the incident having occurred early 
in October, I presume that I witnessed the choosing 
of a hybernaculum by this butterfly. Another interest- 
ing incident in butterfly-life is the occasional by-play 
of these insects during courtship. For minutes at a 
time I have watched the games of two individuals of 
Chrysophanus phleas (Small Copper.) After taking a 
turn or two together on the wing, they seemed intention- 
ally to lose sight of each other when running about on 
leaves of plants, and to play a sort of game of “hide- 
and-seek,” with some intelligence and pleasure in the 
performance. 
Grasshoppers are persistent in seeking warm situations 
in the evening; they will climb walls, trees, and posts, to 
the height of several feet above ground, in order to keep 
within reach of the retreating sunshine. They also vary 
their sibilous trilling, or instrumental music, considerably, 
in the rapidity with which the component sounds are 
given, and in duration ; and they do this more when they 
are not courting than when the male is pursuing the 
female. On the latter occasion the sounds may be given 
with seemingly frenzied rapidity and persistence; but the 
male seems to follow or approach the female with respect- 
ful delay and patience. These remarks apply to the two 
common species, Stexobothrus bicolor and Sten. parallelus. 
I have noticed a variation in note (accompanied by an 
unusual movement of the wings), in the common Hedge 
Cricket (7hammnotrizon cinereus), which is so common in 
autumn. <Acrida viridissima (Green Field Cricket), 
whose loud note is unfortunately less frequently heard 
than we could desire, is evidently an observant and calcu- 
lating creature, as anyone will perceive who stealthily 
approaches one of these animals during its singing, and 
attempts to capture it.
