Final answer:
Atlas moths and Death's-head hawkmoths are the moths among the options given that are rarely encountered in Tennessee because they are native to Southeast Asia, Europe, and Africa.
Step-by-step explanation:
Among the moths listed, Atlas moths and Death's-head hawkmoths are rarely encountered in Tennessee. Luna moths and Emperor moths do exist in the region, but Atlas moths are typically found in the tropical and subtropical forests of Southeast Asia, and Death's-head hawkmoths are more commonly found in Europe and Africa. Both of these species are known for their size and distinct appearances; Atlas moths have one of the largest wingspans of all moths, and Death's-head hawkmoths are known for the skull-like pattern on their thorax.
