Distribution
Recorded from Connecticut, District of Columbia, Illinois, Indiana, and Kansas based on available occurrence data. The scattered distribution pattern suggests it may be associated with particular plants or conditions that are patchily distributed across this range.
Diet
Feeds on plant sap using , as is characteristic of all Membracidae. Specific plant associations have not been documented in the available sources.
Ecological Role
As a phytophagous insect, it functions as a primary consumer in . Treehoppers may also serve as prey for various and as for , though specific ecological interactions for this are undocumented.
