 species probably winters, 

 as a rule, in the atlult 



stage, laying its eggs early in spring. The (irst brood matures the latter 

 half of May. Osborn has noticed another brood, developing to the adult 

 in July. In midsummer all ages and stages may be found together. 

 There are thus two gxMierations in a season, ami ])ossibly three. The 

 species is widely distributed Ihroughoul the I'nited Stales from Cali-

This is a very active, rather fragile looking, soft-v^inged bug (Fig. 105), 

 about a fourth of an inch long and half as wide, brassy brown, and 

 variably streaked and s|)olt(>d with yellow. The wingless young are 

 greenish, and, except in the first stage (Fig. 107), there are five black 

 spots on the back, as shown in the figure (Fig. 108). This sap-sucking 

 bug infests a wide variety of food plants in nearly every sort of situation
