{Dorylus wilverthi polymorphism}Polymorphism

In October 2003, Professor Shigeo Uehara sent me three samples of wilverthi from the Kalinzu Forest, Uganda, these were - III-85, of 19.xi.2002, W. of 519, in forest; III-89, of 19.xi.2002, W. of 430 (T4), in forest; III-137, of 23.xi.2002, Sawmill, in forest. From those I was able to create this polymorphism montage and the other photomontages. What is unusual is that the all the morphs, even the very smallest, have the posteriorly narrowed head, with distinct dorsolateral points.

The various morphs are shown in detail below.
