When it was desired to observe only the emergence of moths, larve 
were placed in a 4-0z. condiment jar containing a bundle of strips of 
strawboard. (Fig. 3.) These cages will be designated as emergence 
cages. 
Fic. 3. Emergence cages. Strips of strawboard removed 
from jars to show arrangement of cocoons and pupa 
cases. 
To secure eggs and note length of life of adults, pairs of moths were 
confined in cages consisting of a cylinder of screen-wire closed at one 
end with screen-wire and at the other end with an apron of cheese-cloth 
which permitted the cage to be fastened over the top of a branch of a 
tree. (Fig. 4.) These will be called oviposition cages.
