Ant queens are among the most long-lived insects known1,2. They mate early in adult life and maintain millions of viable sperm in their sperm storage organ until they die many years later3,4. Because they never re-mate, the reproductive success of queens is ultimately sperm-limited, but it is not known what selective forces determine the upper limit to sperm storage. Here we show that sperm storage carries a significant cost of reduced immunity during colony founding. Newly mated queens of the… CONTINUE READING
