Another lot of 35 moths that emerged April 25 to May 4 gives an average life of days. The life of the moths is largely dependent on temperature. They are able to lay fertile eggs in 3 to 5 days after emergence, but during cold weather in spring or fall they remain torpid for long periods. Moths can be fed by putting into the cage a piece of raw cotton soaked in sirup or fruit juice. However, even without food, if a sufRcient number of moths are confined together, eggs will be laid abundantly. Data on caged spring-brood moths are given in Tables V and VI. These moths issued from the wintering material collected March 24 and March 31. 84606—Bull. 80, pt 1—09 2.
