1 Male had mated previously with another female for 1 hour and 17 minutes. 
2 Many eggs laid, but none hatched. 
3 Male had mated previously. 
Table VII indicates that moths began oviposition a few hours after 
issuance, or at the latest on the following day. The period of ovipo- 
sition of a single moth is seldom longer than two or three days, and 
the moths die immediately thereafter. 
LENGTH OF LIFE OF THE MOTHS. 
Moths which were kept from mating were found to die without hay- 
ing placed any or at least only a few eggs. Female moths die imme- 
diately after oviposition is completed. Males die soon after mating. 
Oviposition within the rearing cages would begin within a few hours (8 
to 10) after mating, and always within 24 hours; it would be completed 
within 3 or 4 days and none was observed to live longer than 5 days.
