Identification

The combination of pale yellow body with dark brown thoracic and abdominal markings, together with geographic distribution in East Palearctic or Nearctic regions, supports genus-level assignment.

Habitat

Nymphs inhabit fast-flowing rivers with large gravel substrate. occur on leaves of trees or shrubs near rivers, and have been collected from small trees and grasses near streams.
