Etymology: Silkmoth is about as transparent as compounds get: it simply joins "silk" and "moth". The interest lies in the second half. "Moth" traces back to Old English "moððe", a word with roots across Germanic languages, and it originally named the small, nibbling insects that ate cloth and wool. Over time, the silk-producing species were identified as a distinct group, and the compound records that they are moths whose product is the very material that moths in clothing were notorious for damaging. The word therefore describes an insect defined by what it makes rather than by its appearance. The caterpillar of this moth spins a cocoon of silk fibre, and the fibre is the reason the insect has been kept and bred for centuries, a practice known as sericulture.
