Ad PHYSIOLOGY OF THE EGGS 
The male is not furnished with this down, as it is 
of no use to him. 
When the female Gipsy Moth is on the eve of 
laying her eggs, she places herself on the trunk of an 
elm or oak, and always with her head downwards. 
In this situation she continues to place her eggs one 
above the other, in the shape of an inverted cone. 
Her fiyst care is to make a small bed of down, into 
which she places the egg intended to form its apex ; 
and the egg being covered with a glutinous substance, 
attaches itself to all the fine downy hair, and at the 
same time adheres to the tree. In this employment 
she continues for many hours, adding to the cone, 
and taking rest at intervals ; and as frequently does 
she protect her eggs by a layer of down. The fol- 
lowing is a representation of the Gipsy Moth, in the 
act of laying her eggs, with the shape of the cone 
when completed. The cut represents the Moth 
half the size of nature.
