Recognition characters: Grayish brown species; length 17–24 mm; mystax white with few black bristles on oral margin; setae and bristles of mesonotum mostly black, some white bristles intermixed posteriorly, postpronotal and supraalar setae white; meral bristles white; scutellar setae mixed white and black, mostly black, marginal bristles white; in males abdominal tergites 2–5 black setae dorsocentrally, segments 6 and 7 silvery white pollinose; legs with femora black; tibiae black, posterior sides pale reddish brown, except the tips.

Distribution: FREMONT: Lander, WANG, LTA, 2 July 2005 ( CSU, GMAD); Riverton, 18 Sept. 1962 ( RJL). GOSHEN: 17 Aug. 1945 ( REP). HOT SPRINGS: Dutch Nick Flats, Big Horn Basin, 14 Sept. 1962 ( RJL). PLATTE: Camp Guernsey, WANG, 2001b ( CSU, GMAD); Chugwater, 5 Aug. 1954 ( WDF); Bowman Ranch, Dwyer, 17 Oct. 1963 ( RJL); Russell Ranch, Dwyer, 27 Aug. 1962 ( RJL); Dwyer, numerous records, 18 Aug.–8 Oct. ( RJL, REP); Glendo, 20 Aug.–11 Sept. 1957 ( DRT); Guernsey, Frederick Ranch, 25 Aug–9 Sept. 1960, 15 Aug.–13 Sept. 1962 ( RJL), 2 Sept. 1964 ( RJL, FRH); E flank of Laramie Peak, Laramie Mtns., 3 Sept. 1964 ( RJL, FRH); Wheatland Canyon, 5 Aug. 1960 ( RJL). Recorded from Wyoming by: Dennis & Lavigne [1975) (as prey of Proctacanthus milbertii  (as Proctacanthus micans  )], (1976b) (pupal case; as Efferia helenae  ); Dennis et al. (2009) (as Efferia helenae  ); Geller-Grimm (2018); Lavigne (1964) (as Efferia bicaudata  ), 1992 (as Efferia helenae  ); Lavigne & Dennis [1975) (as Efferia helenae  ; prey of Pogonioefferia frewingi  (as Efferia frewingi  )], (1994) (as Efferia helenae  ); Lavigne & Holland (1969) (as Efferia helenae  ; as prey of Diogmites angustipennis  ); Lavigne & Pfadt (1966) (grasshopper predator); Lavigne et al. (1994) (as prey of Efferia helenae  ).

Habitat: Douglas fir forest (clearings within the forest where shrubs and grasses are dominant), and gramaneedlegrass-wheatgrass and grama-buffalo grass vegetation types. Open rangeland, the Wheatland area is characterized by blue grama ( Bouteloua gracilis  ), little bluestem [ Schizachyrium scoparium (Michx.) Nash var. scoparium  ( Andropogon scoparius Michx.  )], and yucca ( Yucca glauca Nutt.  ).

Ethology: Rests on and forages from ground, grass mat, and vegetation 12–60 cm above the ground (see Lavigne 1964 as Efferia bicaudata  ; Lavigne & Holland 1969 as Efferia helenae  ).

Prey: The following prey were collected 17 km NW of Wheatland on 21 Aug. 1972: DIPTERA  , Asilidae  : Pogonioefferia helenae (Bromley)  ; HEMIPTERA (Homoptera)  , Cicadellidae  : Cuerna costalis (Fabricius)  ; Gypona melanota Spangberg  ; HYMENOPTERA  , Sphecidae  : Solierella  sp.; Tiphiidae  : Myzinum quinquecinctum  (F.); Tiphia  sp.; ORTHOPTERA  , Acrididae  : unidentified. COLEOPTERA  , DIPTERA  , HETEROPTERA, HOMOP- TERA, HYMENOPTERA  , LEPIDOPTERA  , NEUROPTERA, ODONATA, ORTHOPTERA  (see note under P. bicaudata  ). Most of the prey records in Lavigne (1964) as well as the biological observations refer to P. helenae  instead of P. bicaudata  ; see also Dennis et al. 2009; Lavigne 1992; Lavigne & Dennis 1994; Lavigne & Holland 1969; Lavigne & Pfadt 1966; Rogers & Lavigne 1972 (all as Efferia helenae  ).
