Thoosa Orangetip

Utah denizen Todd Stout's thorough investigation into the Anthocharis sara-complex resulted in confirmation of three species-level orangetips in that complex: sara, thoosa, and julia. Our familiar sara orangetips are basically confined to the western half of California (just extending into Oregon). The sara-like butterfly found (from north to south) in the Kingston range; Clark Mountains; Mountain Pass; Providence Mountains; and Old Woman Mountains in the eastern mojave desert, are thoosa.
