Habitat
have been collected from caves and mesic forest . Darkoneta stridulans from Panama was described from cloud forest. Specific microhabitat preferences for most species remain poorly documented.
Distribution
Western United States (California, Texas), southern Mexico, Guatemala, and Panama. The northernmost records are from California and Texas; the southernmost record is Darkoneta stridulans from Panama.
Behavior
Darkoneta stridulans possesses stridulatory organs, suggesting sound production as a behavioral trait. The function of this stridulation—whether for defense, courtship, or other purposes—has not been determined.
