Cordillacris occipitalis

Spotted Wing Grasshopper

Family: Acrididae · Class: Insecta · Order: Orthoptera

The Spotted Wing Grasshopper (Cordillacris occipitalis) is a member of the family Acrididae within the order Orthoptera. This species belongs to the genus Cordillacris, which comprises grasshoppers adapted to specific habitat conditions in western North America. Physical characteristics of C. occipitalis include the distinctive spotted wing pattern that gives the species its common name. As with other members of the Acrididae family, this grasshopper possesses powerful hind legs adapted for jumping, compound eyes, and chewing mouthparts. The forewings typically display a mottled appearance with dark spots or bands, while the hindwings may show contrasting coloration patterns when extended during flight or defensive displays. The range and distribution of the Spotted Wing Grasshopper within California remains poorly documented in current scientific literature. Limited available records suggest the species may occur in specific habitat types within the state, though comprehensive distributional surveys have not been conducted. Historical collection records and contemporary observations are sparse, making it difficult to establish precise boundaries for the species' California range. Habitat preferences for C. occipitalis have not been thoroughly studied or documented in the available literature. Like many grasshopper species, it likely inhabits areas with appropriate vegetation for feeding and suitable substrate conditions for egg-laying. Many Cordillacris species show preferences for specific plant communities or elevation ranges, but detailed habitat requirements for the Spotted Wing Grasshopper require further investigation. Behavioral and ecological aspects of this species remain largely unstudied. Most grasshoppers in the family Acrididae are herbivorous, feeding on various grasses and forbs. Reproductive behavior typically involves males producing acoustic signals to attract mates, with females depositing eggs in soil or plant tissues. Seasonal activity patterns, preferred food plants, and reproductive timing for C. occipitalis have not been documented in peer-reviewed literature. The conservation status of the Spotted Wing Grasshopper is not currently evaluated by federal or state agencies. The species does not appear on the U.S. Fish and Wildlife Service's list of threatened or endangered species, nor is it designated as a Species of Special Concern by the California Department of Fish and Wildlife as of December 2025. However, the lack of recent comprehensive surveys and limited ecological data makes it difficult to assess population trends or conservation needs. Primary threats to grasshopper species generally include habitat loss, agricultural conversion, urban development, and climate change. Without specific studies of C. occipitalis populations and habitat requirements, potential threats to this species cannot be accurately assessed. The apparent rarity of recent observations suggests either a naturally uncommon species, restricted distribution, or possible population decline. Scientific documentation for this species remains extremely limited. The information presented here is based on taxonomic classification and general characteristics of the Acrididae family. We welcome contributions of verified scientific data, photographs, habitat observations, or distribution records to enhance this species account.
