The name ant-lion is a misnomer; for it creates the impression that this insect feeds exclusively, or almost exclusively, upon ants. Such is not the case. Any small creeping invertebrate—be it insect, crustacean, or arachnid—is acceptable. Several of the most flourishing colonies of ant-lions found near St. Louis are located in the dirt floor of a dilapidated stone-crusher of an abandoned quarry. The diet of the inmates of those pits is composed largely of sow- bugs (Porcellio). Emerton (6) and MacLachlan (i i) fed their ant- lions on living flies that had been disabled; Berce (i) reared his on living flies, wood-lice and earwigs. I supplied mine with. Fig. 5 FIG. 5. Chrysalis of ant-lion that died on way to surface. living specimens of the following invertebrates; caterpillars (even hairy ones), wood-lice, small roaches, small moths (held by the wings until the ant-lion had secured a hold), spiders, nymphal squash bugs, ants, small beetle larvae, soft-bodied beetles, and bed-bugs. All of these were accepted and, after the juice had been sucked from each body, the dried remains were cast out of the pit. The ant-lion has no mouth opening in the true sense of the word. The strong curved mandibles are perforated at the tip,.
