464 ENEMIES OF BEES. 
ten or eleven days: and they often spin so late in the Fall, 
as not to emerge until the ensuing Spring. 
810. In Northern latitudes where the thermometer 
ranges for days and weeks below 10° the bee-moth-worm 
can winter only in the hive near the bee-cluster. Itisa 
fact worthy of notice that Apiaries that are wintered in the 
cellar are more annoyed by the moth during the following 
Summer than those that are wintered out of doors, because 
none of the larve of the moth perish. 
Dr. Dénhoff says that the larvee become motionless at a 
temperature of 38° to 40°, and entirely torpid at a lower 
temperature. A number, which he left all Winter in his 
summer-house, revived in the Spring, and passed through 
their natural changes. This was in Germany where the 
Winters are milder than in our Northern and Middle 
States. 
“If, when the thermometer stood at 10°, I dissected a chrysalis, 
it was not frozen, but congealed immediately afterwards. ‘his 
shows that, at so low a temperature, the vital force is sutiicient to 
resist frost. In the hive, the chrysalids and larvew, in various 
stages of development, pass the Winter in a state of Lorpor, in cor- 
ners and crevices, and among the waste on the bottom-boards. In 
March or April, they revive, and the bees of strong colonies com- 
mence operations for dislodging them.’”? — DonHoFF. 
Some larvee which Mr. Langstroth exposed to a tempera- 
ture of 6° below zero, froze solid, and never revived. Others, 
after remaining for eight hours in a temperature of about 
12°, seemed, after reviving, to remain for weeks in a crippled 
condition. 
‘“« The eggs of the bee-moth are perfectly round, and very small, 
being only about one-eighth of a line in diameter. In the ducts of 
the.ovarium, they are ranged together in the form of a rosary. 
They are not developed consecutively, like those of the queen bee, 
but are found in the ducts, fully and perfectly formed, a few days 
after the female moth emerges from the cocoon. She deposits them, 
usually, in little clusters on the combs. If we wish to witness the
