Early science fiction in the US, possibly "the first robotic insect short story," featuring watchmaking and a small butterfly, so artfully made it is difficult to tell "if it is real or a machine"; a child who "has inherited his father's strength and his grandfather's skepticism" crushes what we will call the clockwork butterfly (quoting the Wikipedia entry).
