Queen and male longevity in the Southeast Asian ant Cardiocondyla tjibodana Karavaiev, 1935


Many species of the ant genus Cardiocondyla are characterized by a bizarre polyphenism with winged disperser males and wingless males that engage in lethal fighting for access to nestmate queens. In C. obscurior, winged males have a stronger life-prolonging and fecundity-enhancing effect for their female mates than wingless males. Here we examine whether the same is true for males of the southeast Asian C. tjibodana. Male phene did not have an effect on queen life expectancy and fecundity. Like the queens of other Cardiocondyla species, C. tjibodana queens were relatively short-lived, with a maximum lifespan of 273 days. Males of both phenotypes survived for a median of 25 days, with one wingless male reaching an age of 194 days. Data from additional species of Cardiocondyla are needed to determine how life expectancy of males and queens and the male influence on queen traits have evolved in this genus.
