Average time spent in the soil days.. 22.21 
The records from Siloam Springs, Ark., are fairly extensive and 
cover the three months, May, June, and July. (See Table XXXV.) 
A total of 5,860 larvae was used, yielding 1,774 adults. The range for 
the various beetles is from 19 to 47 days, with an average for all of 
29 days. In this and other tables on the length of time spent in the 
ground, and also on the time spent in the fruit, the monthly totals 
and averages shown are largely arbitrary, in that the month is based 
upon the time of larva? emerging from the fruit. Larvae leaving the 
fruit in. late May, for instance, would be in the ground during much 
of June.
