SO called on account of the bristles at the hind end of the body. Fig. 34 represents one of the springtails. In these insects there is a taillike organ, which is bent under the insect when it is at rest, and by which it can leap several feet. Spring- tails are abundant in damp places, among decaying veg- etation ; but they are com- monly overlooked on account of their minute size. The name Thysanura is from two Greek words: thysanos, a tassel, and oura, the tail. Order Ephemerida (Eph-e-mer'i-da). The May-flies. The members of this order have delicate membranous wings with a fine network of veins ; the fore wings are large and the hind wings are much smaller, or wanting. The mouth- parts are rudimentary. The met morphosis is incomplete. The name of this order is from the Greek word epheme- ras, lasting but a day. It was given to these insects on ac- count of the shortness of their lives after reaching the adult state. Fig. 35 represents a common species. Work on May-flies is outlined in the chapter on Pond Life. fig. 35.—a 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.
