The spiracles of the abdomen are the most constant, usually occurring in or near the soft membrane between the sternites and tergites; the thorax at most has but two pairs, the head none. In insects with good powers of flight many of the tracheal trunks are expanded to large air sacs, which may be of value as reservoirs of air, so that the ordinary respiratory motions are less necessary during Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Hertwig, Richard, 1850-1937; Kingsley, J.
