Identification
The two species C. flavicornis and propinquilinea are very similar. Both have orange antennae and a circular dark-rimmed white orbicular spot. According to the description on Lynn Scott's site:
"The most obvious difference between the two species is the presence of the very dark "shield" in the median area when C. flavicornis has its wings closed. C. propinquilinea has no bar joining the am and pm lines across the median, and the median area is more or less the same shade of gray from costa to inner margin."
