It is common in woods and feeds upon other insects. Libellulidae. Dragon-flies. Devil's-darning'-needle. Musquitoe- hawks. Demoiselles in France. The head is large and globular, eyes immense, encircling the head ; thorax square, wings large net-veined, equal; abdomen long linear, cylindrical. They are continually flying over pools, hawking for smaller insects in hot summer days, flying often till dusk. Though dreaded by most persons, they are perfectly harmless, though giving a sharp bite with their powerful jaws when held in the hand. " They are difficult to kill, and should be brushed with alcohol or benzine, or killed by ether. The Agrionidac are small slender species of graceful form, and blue, green or bronze or red colored, flying away and alighting upon rushes in the water, and are easy to catch ; they must be pinned carefully, and are very brittle when dry. The large species are hard to catch ; patience and swiftness in the use of the net will soon render the beginner dexterous. These insects have also their subimago state. They should be described in life, as the colors fade rapidly after death. The larvae (Fig. 31) are interesting. They have large jaws, marked by an p immense labium, otherwise the mouth parts are much like grasshoppers, &c. The larva of Agrion is slender and long, with thin caudal lanceolate plates. They all walk over the bottom in search of other insects, and propel themselves more rapidly by ejecting behind them, with considerable force, a stream of the water that has been used for respiration. Ephemeridae or May flies, as their name implies, are very short lived insects. They have weak slender bodies, obsolete mouth- parts as they take no food in the perfect state, minute antennae, the wings are very unequal in size, and the abdomen has two or three long appendages.
