may be seen undeveloped within the chrysalis, as may 
also the antennz, the legs, the segments of the thorax 
and abdomen, and even the spiracles. At this time 
the young butterfly must live by using the stored-up 
energy developed by its enormous appetite in the 
larval stage. The change now going on is termed 
pupation. 
Again moulting occurs, and the imago emerges. 
At first it is soft and flabby, but the blood pumped into 
the baggy wings quickly distends them and they dry 
and harden in the sunlight. The body soon attains its 
full strength and the insect flies away to enjoy a life 
entirely different from its previous phases of existence. 
Now it rejoices in two pairs of large and strong wings 
covered with beautiful scales arranged in regular pat- 
terns. It sucks honey from flowers by means of its 
long coiled proboscis. This interesting piece of 
machinery has already been described. It is doubtful 
if this magnificent aerial creature, leisurely floating in 
mid-air, or bravely buffeting the winds, and sometimes 
sipping a bit of nectar, would recognize one of its 
brothers or sisters in either its gormandizing larval 
stage or its inactive pupal condition. Indeed, the 
graceful mother seems neither to recognize nor to care 
for the offspring crawling from the eggs she deposits 
from day to day. 
Our milkweed-butterfly lives much longer than most 
of her lepidoptera relatives while in the imago stage. 
She even migrates when autumn comes and with others 
of her kindred seeks a warmer climate for the winter. 
Some of those which do not migrate hide in sheltered 
crevices to emerge in the spring battered and frayed, 
but ready to deposit eggs for the new broods which are 
to people the air of the coming summer. 
The Cricket. The common black cticket so often 
seen in the fields and about our gardens in the late 
summer and during the autumn is known as Gryllus 
abbreviatus. His pleasant chirp attracts us to an
