LENGTH OP LIFE OF MOTHS 
The length of life of moths varied from 2 to 15 days, the average 
for those under observation being about 6 days. The data bearing 
on this phase of the life history are insufficient to make any general- 
ization, as only a few observations were made to determine this point.
