Excerpt from The Glasgow Medical Journal, Vol. 85: January to June, 1916 The number of flies in every part of the world is dependent upon the existence of conditions suitable for their development, and it may at once be said. That the whole problem of the house fly as a nuisance and as a menace to health hangs around its processes cf breeding and feeding. A full appreciation of the problem and of the means of its solution rests on an intimate knowledge of these processes. It will therefore be our first duty to make ourselves acquainted with the development of the fly from egg to adult, with the structure and function of certain parts of its body, and with its habits of feeding.
