One of my favorite ant words: dichthadiigyn.
Dichthadiigyn queen ant has a body type with two phases: physogastric & mobile. This is a characteristic of army ants that evolved multiple times!
Army ants stay on the move until they find a rich hunting area. Then the queen settles down & gets too huge to walk for a few weeks. She lays thousands of eggs, the workers from the last cycle emerge. Then she slims down enough to run again with her half a million daughters!
A remarkable transformation!
