Wyoming Satyr - Neominois wyomingo
Considered by most authorties at this time as a subspecies of Neominois ridingsii (Riding's Satyr) that is best differentiated by the late season in which it flies (Opler and Wright 1999; Scott et al. 2008; Warren et al. 2008). See the Riding's Satyr account for full species description; below is description of Riding's Satyr.
[From Ferris and Brown 1981; Scott 1986; Opler and Wright 1999; Glassberg 2001; Pyle 2002] Forewing 1.9-2.6 cm. Uppersurface sandy brown-gray, all wings crossed by postmedian band of oblong creamy-white ovals, two pupiled black spots contained in forewing band, sometimes a small eyespot in hindwing band; undersurface similar but less distinct, with light and dark irregular bands.
One flight; late August to mid-September (Scott et al. 2008). Mid-August to late September (Opler and Wright 1999).
Best determined from other Neominois by the late season that adults are active; from other species best determined by color and uppersurface of all wings crossed by postmedian band of oblong creamy-white ovals, two pupiled black spots contained in forewing band, sometimes a small eyespot in hindwing band (same for Riding's Satyr, N. ridingsii).
Central Montana south to northern Utah, northern Colorado, northwestern Nebraska; to 2515 m elevation in Colorado, to 2438 m elevation in Utah. In Montana, reported from at least nine counties in the southern half of the state, including Lewis and Clark County (Scott et al. 2008).
Short-grass prairie, sagebrush grassland, valley bottoms, flats, grassy swales and gentle slopes (Opler and Wright 1999).
Limited information. Larval food plants include Agropyron. Adults feed on flower nectar, including Chrysothamnus (Opler and Wright 1999; Scott et al. 2008).
Limited information. Females lay eggs singly on dead or dry grass parts. Upon egg-hatch larvae generally do not feed but hibernate as L1 instar (sometimes possibly L2). Males perch and patrol for females mostly in grassy swales, not on hilltops (Scott et al. 2008).
