I have no idea! I was privileged to live in Texas for about a year in 1979/80. I remember a great advertisement for Lone Star Beer in which the fat, tall, old wife of a short, fat, cigar-ed millionaire mocked her husband with, “I know all about the armadillo!”
I do remember a LOT of roadkill armadillos though.
I’ve heard they have an odd habit of jumping and rolling into a ball when frightened, leading to getting embedded in the grilles of oncoming traffic, or worse, ping-ponged into the windshield.
I’ve only seen one live one in person, drove out to New Mexico from North Carolina during summer break when I was in college to visit with my dad in Las Cruces, he was setting up a manufacturing plant and was there for six weeks. That one was grey, almost silvery.
