This set of observations relates to that period regarding 
which Johnston and Tiegs’ paper shows certain gaps. The larval 
feeding stage during October was 8 to 10 days, the prepupal 
6 to 17, and the pupal (October-November) 8 to 10, while the 
total period elapsing between deposition and emergence was 
found to range from 26 to 43 days.
