Sometimes insects of this series are not confined to greenvegetation, as in the case of the clover-hay worm, AsopiacostaUs, which attacks the dry or partially dry product, webbing it up and causing more orFig. 356. less injury. Its near ally, Pyrails farinalis, may befound in barns or binswhere grain is carelesslystored, and the ? caterpil-lars make little tubes,formed partially of silk,partially of fragments ofthe grain and even of en-tire kernels, upon whichthey feed. Rarely, how-ever, are they abundantenough to do serious in-jury, and as against bothcleanliness will go far,while bisulphide of carbonwill readily destroy the larvae.

Salting the first two orthree feet has also been recommended, and will probably beeffective. In
