"The Colorado Beetle is a beetle first described by Thomas Say, in 1824, from specimens found by him near the Upper Missouri. The larva feeds greedily on the potato, and having attracted notice in Colorado for its ravages among the crops of that esculent in the territory, it moved eastward year by year, till in 1874 it had reached the Atlantic seaboard. It is popularly known as the potato bug."—(Charles Leonard-Stuart, 1911)
