SUMMER. 
full-grown worm, while in a lower temperature it 
would require weeks and even months in some cases, 
perhaps from fall till spring. 
TIME OP TRANSFORMATION. 
The worm, after spinning. its cocoon, soon changes 
to a chrysalis, and remains inactive for several days, 
when it makes an opening in one end and crawls out. 
The time taken for this transformation is also governed 
by the temperature, although I think but few ever 
pass the winter in this state. It is a rare thing to find 
a moth before the end of May, and not many till the 
middle of June ; but after this time they £#e more 
numerous till the end of the season. 
FREEZING DESTROYS WORMS, COCOON AND MOTH. 
It is pretty well demonstrated that the moth, its 
eggs, larvae and chrysalis cannot pass the winter with- 
out warmth of some kind to prevent their freezing to 
death. The following facts indicate this. I have taken 
all the bees out of a hive in the fall, and without dis- 
turbing the comb or honey, put it in a cold chamber 
where it could freeze thoroughly. In the following 
March bees were again introduced, and when not on a 
bench with some other stock that had worms, not a 
single instance in forty cases has ever produced a 
worm before the middle of June, or until the eggs of 
some moth matured in another hive has had time to 
hatch. I have sometimes, instead of putting bees in 
these in March, kept them till June for swarms, per- 
fectly free from any appearance of worms 1
