With its large antennae, the species has a distinctive appearance and is readily identified in the field, which accounts for the significant number of iNaturalist records. Conservation status. BC: S3S4 Distributional notes. In British Columbia, Tabuda is probably restricted to dry grassland and forest habitats in the Thompson-Okanagan and Kootenay regions (Chopaka, Spences Bridge, Columbia Gardens north to Kamloops), where it is probably at the northern limit of its range. Ecoprovinces and other designations. BC: Southern Interior, Southern Interior Mountains. Range. Intermontane. British Columbia south to California, Nevada, Utah, Colorado, and Nebraska (Webb et al. 2013). Biological notes. Flight period: 4 April–24 May. Flight is early; only eight of 68 records are after mid-May and none are later than May. The genus inhabits sandy sites (Irwin & Lyneborg 1980). Records in British Columbia are from mostly lowland sites in sandy grasslands (Purshia tridentata, Artemisia tridentata, Pseudoroegneria spicata habitats) and adjacent open Pinus ponderosa and Pseudotsuga menziesii woods (Fig. 16).
