When collected, the larvae that became the atypical colored pupa (from Juglans cinerea), was pre-pupal and had lost its color and pattern. The pupa appears to be extremely different from the typical Satyrium calanus larvae. David Wright says he sees a lot of variation in the pupa of coppers and blues, but not the hairstreaks. Could we have Satyrium caryaevorun in southern NJ? We will have to wait for eclosure to determine this, but even if it is S. calanus it could be interesting.
