Aidemona azteca is diurnal and mostly terrestrial, spending much of its time on the ground or low plants. It tends to remain still when approached, relying on camouflage, but can make strong jumps and short flights if disturbed. Like many ommatolampidines, it is not especially vocal; any stridulation is subtle and infrequently noticed. A. azteca is herbivorous, feeding on a variety of grasses and low-growing broad-leaved plants.
