Castilleja hispida
Also called Bristly Paintbrush, Hispid Paintbrush, Harsh Paintbrush
Castilleja hispida is a species of flowering plant in the family Orobanchaceae, also known by the common name harsh paintbrush, or harsh Indian paintbrush. It is native to British Columbia, Alberta, Washington, Idaho, Montana, and Oregon.
Harsh paintbrush plays an important role in grassland multitrophic interactions. For example, its foliage naturally contains defensive compounds called iridoid glycosides that are sequestered in the tissues of the endangered Taylor's checkerspot butterfly larvae, which have developed a tolerance for these compounds and are able to consume golden paintbrush foliage. These sequestered iridoid glycosides then confer chemical protection against bird predators to the butterfly larvae. Harsh paintbrush is also one of the preferred oviposition species for female Taylor's checkerspot butterflies.
