Collection, of 124 colonies from Bahia, Brazil, between January 2003 & January 2004, revealed that ergatoid males & a few female sexuals were produced throughout the year.  Female sexual production peaked in April 2003, & was followed by a significant decline in colony size, presumably due to colony fragmentation or budding.  Not a single winged male was found, suggesting that in this population, they are indeed reared only under particularly stressful conditions, as previously observed in the laboratory.]1 aHeinze, J1 aDelabie, J H C  uhttps://antkey.myspecies.info/id/content/population-structure-male-polymorphic-ant-cardiocondyla-obscurior
