There are two clavicorn beetles, known, respectively, as the saw-toothed grain beetle and the cadelle, of omnivorous habits and universaldistribution, that commonly occur in dwellings as well as in grauaries,mills, and warehouses. The former is so small as to readily escapenotice except when it is present in numbers j the latter, though seldomoccurring in abundance, is conspicuous, both as larva and beetle, onaccount of its size. The two species resemble each other in beingpartially carnivorous and predaceous, following in the wake of otherinsects like the Indian-meal moth, the cadelle particularly makingatonement for its ravages in the pantry supplies by destroying suchsmall insects as cross its path that it is able to Fig. 58.—Pyralis farinalis: a, egg-mass ; b, eggs, more enlarged; c, eggshowing embryo within; d, larva,dorsal view; e, pupa—all enlarged(authors illustration, reengraved).
