Frequent occurrence of gynandromorphs in the natural population of the antVollenhovia emeryi (Hymenoptera: Formicidae)

Many gynandromorphs were obtained from the natural population ofVollenhovia emeryi (microgyna form) in Gifu, Japan. They were primarily male: most had the thorax and gaster of males, and the head contained tissues partially feminized to varying degrees. These gynandromorphs were found in 27 of 45 colonies studied (60.0%). Their proportion to total males in each colony varied from 3.7–47.7%, with a mean of 21.4% (n = 21). The gynandromorphs were found in all study areas and in every study year, suggesting that gynandromorphism in this species is not a rare phenomenon. Moreover, this observation suggests that gynandromorphs may occur more frequently in micraners than in macraners.
