DRAGON-riY a long abdomen that serves admirably as an aerial rudder, and with strong front legs and great jaws fitted for grasp- ing and biting their victims, they may in- deed appear as formidable dragons to less fortunate insects. In their earlier stages these insects develop in the water, where they are also predaceous. The Dragon Flies are commonly di- vided into two groups: those in which the wings are held vertically when the insect is at rest are called Damsel Flies; those in which the wings are held horizontally when the insect is at rest are called Dragon Flies. Among the many parasitic and predaceous insects to be found amid colonies of plant lice, the Aphis Lions are per- haps l^e most remarkable. These are long-legged, slender-bodied creatures with strange long jaws between which they grasp their prey while they suck the body dry., They are the larvas of the Golden-eyed Lace-winged Flies (^Chryso- pidse). The curious Mantids of the order Or- thoptera are also remarkable predaceous insects. They are closely related to the walking sticks and lie in wait till vari- ous insects come within reach of their grasping front legs. The native Praying Mantis is not uncommon in the South- em states, while another species from Europe has lately been introduced into New York state. There are, of course, many predaceous creatures among. Egg Mass of Mantis.
