Nothing in my Gemmed Satyr photos perfectly matches the Cech/Tudor image of the
inductura variant. However, there seem to be two different forms in the late
season.
I compiled all of my Gemmed Satyr photos (even the bad ones if they showed the
line enclosing the spots), unmanipulated except for cropping, with dates and
locations noted:

Notice the difference in intensity of cross-wing line markings between the two
September 12th individuals (both Union County). This difference can be seen
again between the two September 24th individuals (both Roane County). In both
cases, the individuals were found within about 100 feet of each other. The
difference probably isn't due to wear, since the wings are not tattered.
Possibly gender differences?

Hello everyone,
I never noticed this before, but the Cech/Tudor book "Butterflies of the East
Coast" mentions that the Gemmed Satyr has 2 seasonal forms, namely, a spring
variant 'inductura' and a summer variant which has more of a darkish line
enclosing the metallic spots. [see p. 216]
I have checked my photos, and all I see are the summer form, even in the
spring.
If you have time, would you check through a few photos and see if you have
this spring variant? I will be looking closely this spring. You don't have to
go to the trouble to send the photo, you can just let me know.
Thanks!
