katydid (Scudderia texensis) are taken from the goldenrod. From the 
goldenrod we also take the goldenrod beetle (Trirhabda tormentosa 
var. canadensis) and the case-bearer (Pachybrachys). The lady-beetles 
(Cycloneda, Hippodamia, Megilla, etc.) are common. The clover-leaf 
beetle (Languria mozardi?) (Fig. 305) is also of common occurrence. 
The snout-beetles are represented by the large, elongated Lixus (Fig. 
306), the larvae of which feed in the stalks of rank weeds. 
Fic. 303.—The lady-beetle (Megilla maculata DeG.) and its life history: a, larva; 
b, pupa; c, adult (Chittenden, U.S. Dept. Agr.); enlarged as indicated. 
Fic. 304.—Meadow grasshopper (X7phidium strictum Scud.); twice natural size 
(after Forbes). 
The onion-fly occurs in connection with the prairie onion. ristalis 
fenax is common on the flowers. Various flower-flies occur. Waiting 
in the flowers for such animals as may come are the ambush-bugs (Phy- 
mata erosa fasciata), and the crab spiders (Misumessus asperatus and 
Runcina aleatoria). The jumping spiders (Phidippus podagrosus) are 
also predatory (138). The orb-weavers (Epeira trivittata, Agriope 
trifasciata) build webs into which many insects fall.
