Identification
Psoloessa species are similar, but adults are more common earlier in spring (usually); rear of pronotum is more angled, with only one cut through median carina and lateral margins of top (more in Eupnigodes), with principal sulcus cutting median carina in front of middle; antennae are not white; hind tibiae are pale, brownish, or reddish/red, but never bluish or purplish.

Ageneotettix deorum is very similar, but averages more stocky in build; head rounder, with the eyes more widely separated and fastigium larger. The hind tibiae in Eupnigodes vary in color, but only rarely distinctly and entirely red. Hind tibiae of Ageneotettix are red (at least in adults).

Aulocara have longer darker antennae and distinctly blue hind tibiae.
Range
Grassland areas in California
Life Cycle
Apparently overwinter as eggs, with adults late spring to early winter (usually most common in late summer)
