A very complete publication @agmoore, in this writing you reveal one of the groups of the class of insects that are usually very detested by people because of the great damage they can do in wooden structures, in my country there are no houses of this material, but termites make theirs with chairs, books or tables if appropriate measures are not taken. Excellent that you mention the change of termites from Isoptera (infraorder) to Blattodea (order), becoming part of the taxon that groups the popular cockroaches, to cite examples.
The termites are part of the very striking insects for being eusocial, thus, from being a single organism, when they unite for a cause they become what is usually called "superorganism" because they act disciplined and together, the same thing happens with ants, bees, etc.
The thing about termite mounds in Australia is really amazing, I didn't know that, although in Australia you always see very fascinating things in terms of animals, they have a very striking and unique diversity. I really liked your post, that's why I shared it a few days ago also on my blog. A hug and good weekend @agmoore.
