| description |
The crown is yellowish with dark brown to fulvous markings that contrast with two diagonal light markings and a pale midline. The pronotum is also yellow, sometimes darker than the crown, with three noticeable longitudinal lines; the scutellum is yellow. The face is also yellow. The wings are semihyaline with a fulvous tinge, yellowish overall; there are many small dark dots and prominent white areolar dots scattered throughout (the veins and markings consist primarily of dots). The male subgenital plates are largely triangular, slightly divergent from one another. The female pregenital sternite has the lateral margins convex and the posterior margin with a small lobe on either side of a median notch. Adult males are 4.0 mm long, females are 4.5 mm; some individuals are less than 4.0 mm. (Hepner 1947)

| distribution |
Primarily eastern and central North America |
| abundance |
Recorded from a couple counties in the Piedmont and Coastal Plain; probably under collected and therefore more abundant in the right habitat. |
| seasonal_occurrence | |
| habitat |
Open grasslands (Hepner 1947) |
| plant associates |
Grasses, in particular Andropogon scoparius, Bouteloua hirsuta, and B. curtipendula; the latter two grasses are the more common hosts. (Hepner 1947) |
| behavior |
Can be attracted at night with a light. |

NOTE: This species resembles S. acutus but is smaller (S. acutus: 4.5-5.2 mm, S. cinereus: 4.0-4.5 mm), yellowish in color rather than orange-brown, the scutellum in cinereus is yellowish while in acutus it is orange, there is not a large contrast between the color of the face and rest of the body in cinereus since they are both yellowish, and the markings on the wings consist primarily of dots (S. acutus has dots but overall is appears uniformly colored since the base color is prominent). (Hepner 1947) |
