Pontiac Directory 01
In either case the creature thinks itself safe, but is sure to be found out sooner or later; nor is it easy to explain this mockery save by reflecting that everything must have its meat in due season, and that meat can only be found for such a multitude of mouths by giving everything as meat in due season to something else. This is like the Kilkenny cats, or robbing Peter to pay Paul; but it is the way of the world, and as every animal must contribute in kind to the picnic of the universe, one does not see what better arrangement could be made than the providing each race with a hereditary fallacy, which shall in the end get it into a scrape, but which shall generally stand the wear and tear of life for some time. "Do ut des" is the writing on all flesh to him that eats it; and no creature is dearer to itself than it is to some other that would devour it.
Each of the winter forms of insects above mentioned can withstand long and severe cold weather--in fact, may be frozen solid for weeks and retain life and vigor, both of which are shown when warm weather and food appear again. Indeed, it is not an unusually cold winter, but one of successive thawings and freezings, which is most destructive to insect life. A mild winter encourages the growth of mould which attacks the hibernating larvae and pupae as soon as, from excess of rain or humidity, they become sickly; and it also permits the continued activity of insectivorous mammals and birds. Thus, moles, shrews, and field mice, instead of burying themselves deeply in the ground, run about freely during an open winter and destroy enormous numbers of pupae; while such birds as the woodpeckers, titmice, and chickadees are constantly on the alert, and searching in every crevice and cranny of fence and bark of tree for the hibernating larvae.
