Identification
Key to eastern spp. adapted from(1):
body elongate oval; head more elongate, juga equaling tylus; anterolateral pronotal margin straight or nearly so; beak reaching at least middle coxae ... ... hilaris
body broadly oval; head short, broad, juga slightly longer than tylus; anterolateral pronotal margin strongly arcuate; beak not surpassing middle coxae ... ... pensylvanica
scent gland channel extends more than half-way to edge of metapleuron

(shorter, more rounded in Nezara)(2)
scutellum has pale dot in each basal corner; antennomeres 3 & 4 blackish, and color is restricted to apical half of segments; connexivia usually with conspicuous dark dot on apical margin of each segment; side of pronotum straight or slightly convex in anterior half; second abdominal sternite has pointed medial spine; ventral scent gland pore long and curved
Range
throughout US & adjacent Canada (NS*-FL to BC-CA), ne. Mexico(3)(4)(*BG data)
Habitat
Woodlands, edges, cultivated land
Season
late Feb to Nov(1)
Food
extremely polyphagous: recorded from 20 plant families(5); adults and older nymphs prefer developing seeds and fruit. May be a pest on soybean, cotton, fruit trees (esp. peach), and many vegetables(6)(7)
