At the beginning of May, there are 259 butterflies.
During the month:
- 45 emigrate, which means they leave the area, so the population decreases: 259 - 45 = 214
- 10 die, which means they are no longer part of the population: 214 - 10 = 204
- 67 immigrate, which means they come to the area, so the population increases: 204 + 67 = 271
Therefore, the population size at the end of the month is 271.
