Remarks
The species are often best identified only upon knowledge of the host plants. They can sometimes be identified based on color patterns, but the differences are subtle. When using color patterns for identification, series of specimens from each population are desirable. So, regard my identifications with a great deal of caution. --S.M. Clark, pers.comm. to =v=
