As the instinct of the flesh-fly directs her to a putrid carcass to deposit her eggs, that her offspring may have their proper food, so the moth seeks the hive containing combs, and where its natural food is at hand to furnish a supply. During the day a rusty brown miller, with its wings wrapped close around the body, may be often seen lying perfectly motionless on the side of the hive on one corner, or the under edge of the top, where it projects over--they are more frequent at the corners than anywhere else, one-third of their length projecting beyond it; appearing much like a sliver on the edge of a board that is somewhat weather-beaten. Their color so closely resembles old wood, that I have no doubt their enemies are often deceived, and let them escape with their lives. As soon as daylight shuts out the view, and no danger of their movements being discovered by their enemies, they throw off their inactivity, and commence searching for a place to deposit their eggs, and woe to the stock that has not bees sufficient to drive them from the comb. Although their larvæ has a skin that the bee cannot pierce with its sting, in most cases, it is not so with the moth, and of this fact they seem to be aware, for whenever a bee approaches they dart away with speed ten times greater than that of any bee, disposed to follow! They enter the hive and dodge out in a moment, having either encountered a bee, or fear they may do so. Now it needs no argument to prove that when all our stocks are well protected, that it must be a poor chance to deposit eggs, on the combs of such hives, where their instinct has taught them is the proper place. But they _must_ leave them somewhere. When driven from all the combs within, the next best place is the cracks and flaws about the hive, that are lined with propolis; and the dust and chips that fall on the floor-board of a young swarm not full will be used. This last material is mostly wax, and answers very well instead of comb. The eggs will here hatch and the worms sometimes ascend to the combs; hence the necessity of keeping the bottom brushed off clean. It will prevent those that are on the bottom from going up; also the bees from taking up any eggs, if this should happen to be the method. I can conceive of no other way by which they get among the combs of a populous stock; where they are often detected, having been deposited by some means. A worm lodged in the comb, makes his way to the centre, and then eats a passage as he proceeds, lining it with a shroud of silk, gradually enlarging it, as he increases in size. (When combs are filled with honey, they work on the surface, eating only the sealing.) In very weak families this silken passageway is left untouched,--but removed by all the stronger ones. I have found it asserted that "the worms would be all immediately destroyed by the bees, were it not for a kind of dread in touching them until compelled
