[4][5] The species has significant size and color variation, thought to be due to environmental conditions, particularly the effect of aridity.

[6] The male of the species has normal, fully developed tegmina and wings, and a tuft of hairs on the back of its middle abdomen.

[6] The general coloration in the male can vary from shining dark brown or blackish to a pale yellowish to slightly reddish tan.

[6] Females of the species have very greatly reduced tegmina, represented by lobe-like lateral pads, and no hind wings.

[7] Adult males lived separately from females and nymphs; they were attracted to light, and would sometimes perch on chaparral plants at night.
