Relations of Man to Insect World.--But Few Species Useful to Man.--Little Trace of Domestication.--Honey-bees: their Origin; Reasons for no Selective Work; Habits of the Species.--Silkworms: Singular Importance to Man; Intelligence of Species.--Cochineal Insect.--Spanish Flies.--Future of Man relative to Useful Insects. Although the relations of man to the insect world are prevailingly those of hostility, there are a few of these multitudinous creatures which have been more or less completely adopted into his great society. Although not more than half a dozen out of the million or more species in this subkingdom have thus been brought to the uses of civilization, the forms are interesting not only for what they give, but for the promise of further contributions when this great problem of winning help from the insect world receives adequate consideration. As a whole, the insects are not well fitted to serve the needs of man. Owing to certain peculiarities in their organic laws they, fortunately for ourselves, are very limited in size. Although some of them afford savory food and are occasionally eaten by savages, and even by civilized folk when pressed by hunger owing to the famines which the invasions of these animals occasionally produce, they can never be of any value as sources of provisions, except through the stores which they accumulate in the manner of the bees. All that we have won, or are likely to win, from this realm is from the filaments which the creatures spin, the wax or honey which they accumulate, the coloring or other matters which their bodies afford, or the help which they may give us in our struggle with invading species of their class.
