XVs- C, adult, slightly enlarged. {A and C from Kellogg, "American Insects," by the courtesy of Henry Holt & Company; B, original.) on plants and mounted on a long stalk, which insures immunity from the attacks of enemies. The order also includes the ant lions, the larvae of which live in the ground, concealed at the bottom of conical pits (Fig. 200). They feed upon insects which when running over the ground fall into these pits. The victim slides to the bottom of the pit, where it is seized by the ant-hon larva and sucked dry, after which the body is thrown clear of the pit by a jerk of the head of the captor. The pits are excavated by the throwing out of the grains of earth in a similar fashion and natur- ally are found only in loose, sandy soil. They are also placed under overhanging ledges of rock or under vegetation where they are protected from rain. Frequently many occur within a small area. The pits increase in size with the growth of the larva until they reach a diameter of from two to three 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 Wolcott, Robert Henry, 1868-1934; University of Nebraska (Lincoln campus).
