Identification
Members of Crophius can be distinguished from other Oxycarenidae by -level morphological characters; specific diagnostic features require examination of detailed taxonomic keys. The Oxycarenidae is characterized by small to medium size, oval to elongated body shape, and typically reduced wing venation.
Habitat
of at least one (Crophius scabrosus) are common in crowns of bunchgrasses, particularly Panicum virgatum and Schizachyrium scoparium. They have also been found on juniper, pine, and composite plants in grassland and open woodland settings.
Distribution
Western and central United States, with documented records from Kansas, Wyoming, Nebraska, and Vermont. The full range of the is incompletely known due to limited sampling.

Data gaps
Critical information is missing for all . No nymphs have been collected despite targeted fieldwork, suggesting either cryptic nymphal , seasonal disconnect between and nymphal occurrence, or extremely low densities of stages.
