Distributional notes. Spiriverpa cinerascens is a widespread species across southern British Columbia from Vancouver Island (Courtenay, Duncan) east to the Columbia River (Revelstoke, Robson) and north to the Cariboo (Quesnel). The species is reported from “ Alaska ” ( Webb et al. 2013) but we have found no evidence in the specimens examined, databases, or literature (e.g. Webb 2005) to substantiate this claim. The lack of other northern records suggests that this is an error.

Ecoprovinces and other designations. BC: Coast and Mountains, Georgia Depression, Southern Interior, Southern Interior Mountains, Central Interior.

Range. Cordilleran. British Columbia south to Arizona and California ( Webb et al. 2013).

Biological notes. Flight period: 8 April–20 August. Habitats include dry creek beds ( Webb 2005), lakeshores, and streambanks.
