. Animal communities in temperate America : as illustrated in the Chicago region; a study in animal ecology. Animal ecology; Zoology -- Illinois Chicago. 290 Fig. 290.—Larva of the salt-marsh caterpillar (Estigmena acraea Dru.); natural size (after Forbes). Fig. 291.—Adult female of the same; natural size (after Forbes). Aphids occur and with them are the syrphus flies, lady-beetles, and other aphid enemies (164), which are discussed more fully in connection with high prairies. The bright green beetle [Chrysochus auratus) feeds on the small-leafed milkweed. One of the corn "bill- bugs" (174) or snout-beetles {Sphenophorus pertinax Oliv.), another snout-beetle (Cryptocephalus venustus), common garden pests, as well as the leaf-beetle (Typophorus canellus) are common (174). One of the most characteristic groups of the low prairie is that of the grass-feeding larvae. The first of these to appear in spring is the grass.
