Driver ants (Dorylus) belong to the same general part of the ant family tree as the South American species we’ve been discussing this week, although both lineages are so old that they last shared an ancestor before plate tectonics tore the two continents apart.
Because Dorylus 1) are nomadic, 2) forage in groups, and 3) reproduce by colony fission, they are true army ants. What’s more, the immense colonies of some species positively dwarf those of their American counterparts. For sheer spectacle, Dorylus raids can’t be beat.
Thanks, Neil, for sharing!
