This (the moc) creature is a flying herbivore that likes tangerine salads, eating leaves, and releiving himself after a good meal. We all know, from the first picture, that he may eat way to much than he should, but he woulden't be the largest ant in the world if he didn't eat that much...
Such is the strength of the ant's jaws, in East Africa they are used as natural, emergency sutures. Maasai moran, when they suffer a gash in the bush, will use the soldiers to stitch the wound, by getting the ants to bite on both sides of the gash, then breaking off the body. This seal can hold for days at a time.
Several species in this genus carry out raids on termitaria, paralysing or killing some of the termites and carting them back to the nest.
