Fig. 87 represents one of our larger species with the wings of one side spread out. When at rest these in- sects fold their wings upon the back, as shown on the left side of the figure. Most of our species are much smaller than the one represented here, but they can be recognized as stone-flies by their resemblance in form to this one. The body is flattened, elongate, and with the sides nearly parallel; l^he prothorax is large ; the antennas are long, tapering, and many jointed ; in most species the caudal end of the abdomen is furnished with two slender appendages. Stone-flies are so called because they pass their early stages beneath stones in streams and ponds. 1. Collect as many kinds of stone-flies as you can, saving several specimens of each kind. 2. Make notes on their powers of flight. 3. Make notes on the localities in which they occur. 4. Try to discover the method in which they lay their 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 Comstock, John Henry, 1849-1931; Comstock, Anna Botsford, 1854-1930.
