Synonyms and other taxonomic changes

Trimerotropis diversellus Hebard, 1928, described from Lower Geyser Basin, Yellowstone National Park, 7200 ft., Wyoming.

Size

about 26 mm males

about 33 mm females

Identification

Not likely to be confused with any other species that occur with it. Small, slender, shades of white, gray, & light brown with dark cross bands on tegmina. Hind tibiae yellow occasionally to brownish. Hind wing yellow with dark band that is widest near outer margin of wing.

T. pallidipennis is found occasionally in the area, but occurs mostly at lower elevations below the mountains. It is usually larger, has longer narrower wings, and with a more curved and usually narrower dark cross band on the hind wings. It has a proportionately smaller head.

Range

Wyoming, Montana, and perhaps Idaho in region of Yellowstone National Park.

Habitat

Exposed rock and gravel areas. Mostly found on pale calcareous rock deposits and gravels associated with geothermal activity, particularly in and around geyser fields.

Life Cycle

Overwinters as eggs in soil. Adults summer to autumn.

Remarks

Basically identical to and apparently closely related to Trimerotropis saxatilis, differing only in smaller average size (but within the range of size for that species). Mainly distinguished by where found.
