1852. Other caterpillars, although not found in gardens, are prejudicial in various ways. The larva of the ghost moth (Hepialus humuli F.) attacks and does much mischief to the roots of the hop plant. The gigantic Goat moth (Cossus ligniperda F.), as a caterpillar, lives entirely within the trunk of the willow, and soon brings it to decay: the same tree is also inhabited by one of the clear-winged hawk moths (Sesia crabroniformis F.). A small moth (Pyralis secalis F.) eats the culm of the rye within the vagina, and thus destroys many ears; while our woollen garments, furs, feathers, and even books, are sometimes ruined by the depredations of three or four other little moths, unfortunately too well known in our dwellings.
