Explanation of Names
Author: Hampson, [1893]

Lymantriinae is from Lymantria Huebner, the genus of the Old World (and introduced to North America) Gypsy Moth, Lymantria dispar. The origin of this name is not obvious. Perhaps from Greek lyma meaning destruction or filth (2). There is also a Greek word liman, meaning estuary, or referring to a particular European estuary, that of the Dnieper (Oxford English Dictionary).

"Tussock moths" for the tufts of hair on the caterpillars. (tussock = a tuft or clump of green grass or similar verdure, forming a small hillock--Wiktionary.) Another name used for the adult moths (esp. Orgyia)is, or was, "vaporers" or "vaporer moths" for the "vaporing" flight pattern (3).
