Lachish and siafu termite-colony raids share nearly identical defensive structures.

Evidence

The similarities between these two battles are striking: both involved a sedentary population defending itself against attack from a larger, invading army. Both cities were surrounded by rigid walls, which restricted entry to a small number of heavily fortified gates. And, in both cases, the fortifications ordinarily sufficed, protecting inhabitants against the majority of likely threats. — Emlen, Douglas J, Animal Weapons_ The Evolution of Battle, 485
