In the vicinity of Rincon Creek and Pueblo Slough, Humboldt Co NV, September 2025.
Of note is the presence of the Bleached Sandhill Skipper (Polites sabuleti sinemaculata), a sensitive subspecies. The range for this subspecies consists of the saltgrass and shrubs surrounding Pueblo Slough, Rincon Creek, and Gridley Lake. Additional populations are likely to occur within similar saltgrass habitats in the vicinity and may extend across the Nevada border into Oregon. Rogue Biology is interested in further documenting species occurrence to better inform management of the extent of range for this under-studied species, please reach out via the contact page if you are interested in collaborating.
