. Elementary entomology . Fig. ii8. A scorpion fly {Panorpa riifesce)is) (Twice natural size) (After Kellogg) gold, from which they are sometimes called golden-eyes.

The adults seem fully aware of these canni- balistic tastes, for they lay the little white eggs on stalks about half an inch high, placing them out of the reach of the larvae. In the undisturbed dust beneath an old shed, or beneath cliffs, or along warm banks, one will frequently find the little funnel-shaped pits of the ant-lions {Myj'viclcouidac), some- times locally known as " doodle ; At the bottom of the pit may be seen two out- stretched jaws awaiting any unwary insect which may slide down the crumbling sides. The larvae are not unlike those of the aphis-lions in general appearance, but have a larger abdomen and a small thorax and slender legs. The adults are dusky-colored, with long, narrow, delicate wings. They are poor fliers and are often attracted to lights (Fig. 116). The scorpion-flies (order Mecoptera) are readily distinguished by the long head, which is prolonged into a beak, at the end of which are the biting mouth-parts. They receive their common name "scorpion-flies" from the terminal segment of the males of the most common forms, which is enlarged and bears clasping organs, so that it looks like the fang at the tip of the body of a scorpion. They are entirely harmless, however, being car- nivorous both as adults and as larvae. The adults are most commonly found on foliage in shady places, though they not infrequently fly into lights, while the larvae look much like caterpillars and live in the soil. The caddis-flies (order Trichopterd) i have wings with but few cross veins but more or less densely clothed with hairs, thus being related 1 From t/irix (a hair) \dpieroii (a wing).
