In feeding, they puncture the leaves and suckout the sap, causing the plants to wilt, turn brown and early spring and late fall broods deposit their eggs incracks of the soil. The other broods place their eggs in theheads of various wild plants. The egg is described as beijigslender, cylindrical, irregularly wrinkled and tapering at bothends; it is vellow in color, orange-red at the anterior Fk;. 39. — The falsechinch-bug, adult(X 11). 48 MANUAL OF VEGETABLE-GARDEN INSECTS The younfi; nymplis are yellowish markerl with indistinctloniijitiulinal dark lines. They feed almost exclnsively onweeds such as pepper-grass, shepherds purse, Russian thistleand sage brush. The older nymphs are more distinctlymarked with brown and reddish lines. When mature, thebugs scatter to all kinds of vegetation but in cases of droughtare forced to congregate on cultivated plants. In Illinois thefirst brood nymphs mature in the latter part of May and thesecond in July. The broods overlap so that in midsummerall stages may be found together. In Kansas there are saidto be at least five generations annually. In Colorado there is a smaller race of the species which bearsthe name Nysius mimdus Uhler. It has been recorded as veryinjurious to beets grown for seed. Control. Much can be done to prevent injury by the false chinch-bugby clearing the fields of all rubbi
