Habitat
Found in open field and dune environments. Has been documented in recently disturbed where it occurs in sympatry with Trimerotropis maritima. Associated with desert grassland based on behavioral studies.
Distribution
North America. Documented occurrence records from Colorado, Idaho, and Nebraska.
Behavior
Exhibits displays that function in reproductive contexts. Studies suggest presumed sex-role reversal in which females may perform aerial typically conducted by males in other . Communicates through species-specific signals, though detailed mechanisms are not extractable from available sources. Hybridization with Trimerotropis maritima has been observed in .
