Eastern
C. hilaris can be differentiated from
C. marginata based on antennal color (bands black and yellow/white in
C. hilaris vs black and green in
C. marginata) but many western
C. hilaris exhibit coloration more consistent with
C. marginata. Genetic divergence suggest presence of a cryptic species
(7). It is unclear whether these populations represent subspecies or cryptic species. Users are encouraged to post more photos of
C. hilaris genitalia.
