Figure 43 gives the cumulative number of workers, nonworkers, and males to have emerged on this nest against time. Workers began to emerge on 3 November 1968 and continued at a fairly steady rate, averaging per day, until 31 January, when the last worker emerged. During the period before any nonworkers or males appeared, the increas- ing number of workers (Fig. 38) caused a decrease in NwM/W (Fig. 26A). On 30 November the first nonworker (no. 8) emerged. She challenged no. 1, the founding queen, and on 12 December superseded her as queen. Nonworkers con-. Figure 43. Adult emergence, colony 268.

Since the combined rate of emergence of nonw orkcrs and males was greater than six times the rate of emer- gence of workers, the net rate of increase of nonworkers and males was greater (Fig. 38) and NwM/W graduallv increased (Fig. 26A). After 25 January nonworkers began to emerge at the increased rate of almost per day (Fig. 43). Males continued to emerge at their high rate. At about this time the number of ^^'orkers on the nest was at its maximum of 15 (Fig. 38). After 31 January no more workers emerged and their numbers b
