Explanation of Names
Strymon solitario Grishin & Durden 2012
named after the geologic feature in the Big Bend Ranch State Natural Area, Texas (The Solitario), where specimens were collected by CJD.
Although holotype was ultimately selected from the Big Bend National Park, "solitario" rhymes with serapio, which is the species group S. solitario belongs to. (Grishin & Durden 2012)
is a large (~14 km dia.) geologic formation
straddling Presidio and Brewster counties in Big Bend Ranch State Park
Type series (30 males and 36 females) from Presidio and Brewster counties, west Texas (Grishin & Durden 2012)
Also, apparently present near Ciudad Victoria, Tamaulipas, Mexico based on photos. (Grishin & Durden 2012)
Arid, desert and rocky slopes (Grishin & Durden 2012)
Over the years, specimens in the Big Bend area have been recorded from February to June and from September to November with majority of records being in late March–April and then September, with early and late dates being 18-Feb-2005 and 9-Oct-1944. No records are available for July, August, December and January. (Grishin & Durden 2012)
Flowerbuds, ﬂowers and fruits of Hechtia texensis (Bromeliaceae) serve a viable larval food source (Grishin & Durden 2012)

Life cycle from oviposition to adult took about 50 days at 70F in a Dallas, TX laboratory. Larva went through 5 instars which may be attributable to laboratory rearing conditions as the overwhelming majority of Lycaenidae are known to have 4 instars with just a handful of exceptions. (Grishin & Durden 2012)
Type Locality: TEXAS: Brewster Co., Big Bend National Park, ca. 2 miles west of Boquillas Canyon.
Per Grishin & Durden (2012), the holotype locality is "a limestone hill immediately to the north of the paved park road leading to Boquillas Canyon, ca. 1 mile east of SH118, near Barker House, GPS around 29°11'50"N 102°57'06"W, elevation 620m."
