Mayer™ found that most of the C. promethea lived about 3 
days. Table 11 shows that the life of these insects varied from 
2 to 11 days, with the mean falling at 4.8 days. These were kept 
in confinement; Mayer does not state the source of his data. 
The accompanying table correlating the length of life with the 
time of emergence shows no relation between these two factors.
