Pheidole sp

Most species of the Pheidole genus are dimorphic and it has been reported that less than one percent of this vast genus is trimorphic. There are six or seven known species of Pheidole that are trimorphic and these are mostly found in North America. All these known trimorphic species have two major worker expression namely the major and super major.

In this very rare trimorphic species there are three morphological expression of the worker's caste. But most unusual is that beside the typical minor and major workers expression there is a median worker expression. The major workers are characterized by large gaster that are approximately the same size as their heads. This disproportionately large gaster is also in the median worker.
