Synonyms and other taxonomic changes
Trirhabda pilosa vitatta Hogue, in Hatch 1971
Identification
The nominate subspecies T. pilosa pilosa has elytra dull-greenish except for the typical narrow yellow lateral margins and an attenuated pale yellow streak (or "vitta") along the midline of each elytron, extending from the base to near the middle.
In subspecies T. pilosa vittata, the pale yellow vitta is wider and more pronounced, and continues to near the apex of the elytra.
Range
Hogue(1) describes the range as "throughout the northern part of the Great Basin", but gives records only for Idaho and the Sierra Nevada mountains of California. Blake(1931) originally included Wyoming in the range of the nominate form of T. pilosa.
Food
Sagebrush (Artemisia tridentata)
Remarks
Hogue(1)(1970) augmented the circumscription of Blake's T. pilosa to include the additional subspecies T. pilosa vittata. It was formally published by Hogue in his treatment of Trirhabda appearing in Vol. 5 of Hatch's "Beetles of the Pacific Northwest"(2).
