Economic Importance:
Limited.
Known host plants:
- Orgerius foliatus – Atriplex canescens (Pursh) Nutt. (fourwing saltbush, Chenopodiaceae)
- Orgerius sp. – Cirsium sp. (thistle), Cirsium occidentale (Nutt.) Jeps. (as Cirsium californicum A. Gray and Cirsium proteanum J.T. Howell; cobwebby thistle) (Asteraceae)
- Opsigonus spp. – reported from Atriplex canescens (Pursh) Nutt. (fourwing saltbush, Chenopodiaceae)
Hosts from Wilson et al. (1994) and Emeljanov (2006); plant names from USDA PLANTS or Tropicos.
Recognition:
Brachypterous, leaving several terga visible from above, tegulae hidden (all Orgeriinae); callosity present behind eye; vertex short, less than 2x length of the eyes.
Keys to genus of US Orgeriinae in Doering & Darby 1943 and Doering (1955). Emeljanov (2006) established subgenera for Orgerius. Species determination can be challenging.
Key to subgenera from Emeljanov 2006
1. Medial abdominal group of sensory pits number 3 + 1 pit; upper part of lateral carinae of metope weak, but distinct; hind tibia with 7-8 lateral spines connected in basal half by foliate ridge … Subgenus Orgerius
1′- Medial abdominal group of sensory pits number 3 pits; upper part of lateral carinae of metope indistinct; hind tibia with 5-6 lateral spines without connecting ridge … Subgenus Opsigonus (type Orgerius minor Ball)
Emeljanov (2006) notes that subgenus Orgerius is Californian, inhabiting chapparal and woody gtades; subgenus Opsigonus is deserticolous, living on Atriplex canescens.
The following from Ball and Hartzell 1922 (keys reformatted):
Description of genus Orgerius:
Resembling Deserta, but with a broader, shorter, distinctly triangular cephalic process.
Cephalic process short, broad at the base, tapering to an angular or slightly conical point, not truncate. The lateral carinas of the front rounding into the median carina at the apex of the cephalic process. Oblique carina curving upwards from the eye, pustulate below; median carina extending to the apex. Eye separated from the pronotum by a diamond-shaped callosity. The anterior margin of the lateral tablets of pronotum transverse instead of inclined posteriorly as in Deserta. Carinae of scutellum sharply defined. Elytra brachypterous, irregularly reticulate. Abdomen obese, oval. Rostrum equalling the abdomen. Anterior femora expanded three times the width of the tibia ; post tibia flattened, inclined to be serrate, the serrations crowned with 6-8 black spines.
This genus was described by Stal for O. rhyparus from San Francisco. Oshanin, 1913, in a review of the group evidently misinterpreted the character of the genus as he describes Orgerius as wanting a callosity behind the eye, while he erects a new genus, Nymphorgerius, for species with short, angular vertices and the eyes bearing posterior callosities. He mentions a carina between the antenna and the eye, which is lacking or but feebly developed in our species and it is probable that the true Orgerius does not occur in Europe.
Key to the Species of Orgerius.
1. Size variable. Vertex narrow, one-half longer than its width; the hind tibia distinctly flattened basally, the heavy spines appearing as serrations … Orgerius s.s. (as Orgerius rhyparus)
1′-. Small, pale, vertex wider, less than one-half longer than its basal width; posterior tibia not modified … O. minor Ball (Emeljanov’s Opsigonus)
Key to Varieties (of Orgerius rhyparus).
1. Large, obese forms, partly rufous or testaceous … 2
1′- Without reddish shade … 3
2. Species entirely rufo-testaceous … Orgerius rhyparus Stal.
2′- Rufous with elytra black … Orgerius rhyparus var clitellus (now a syn. of Orgerius rhyparus)
3. Uniformly fuscous, size variable … 4.
3′- Uniformly pale or fuscous and pale, small … Orgerius ventosus
4. Large, obese, females, 5 mm. or longer … Orgerius concordus
4′- Small, females 4 mm. or less … Orgerius pajaronius

Collecting
Collected infrequently (but more common than many U.S. Orgeriinae), found by inspecting, sweeping or beating hosts.
Molecular resources:
As of this writing (3 Oct. 2018), data for only Orgerius proprius is available on Genbank, and this same species on Barcode of life.
