The Tiger Swallowtail (Papilio glaucus) is quite a variable
butterfly species with 2 color forms of the (female), a
recognised subspecies (maynardi), a seldom
encountered (smoky/transitional) form, rare occurring examples
which feature genetic anomalies on the wings, and lastly incredible
gynandromorphs.

Quite the butterfly species.....

"Smokies" are tigers which exhibit a "transitional" form with traits of
(both) color phase (females). They are seldom encountered in nature
(generally) so, they are held in high regard by "field men" of the net.
You've got a lot of luck on your side basically to ever run across one but,
it happens (here and there) and usually in mid or late summer.

What I provide here for those interested is a look at 2 (spring) generation
specimens which were caught MANY years apart by the same collector at
just about the same time of year !

These were both caught on location of a field in Columbia, Missouri.
Unlike, the summer (size) adults which are likewise seldom seen THESE
are only the size of your typical Mourning Cloak (N. antiopa).

Beautiful specimens Trehopr.

While maynardi is a subspecies of Papilio glaucus, appalachiensis is recognised as a separate species which originated from hybridisation between ancient glaucus and canadensis at least 10,000 years ago.

Thank you Adam for your expertise.

I have been unaware that "appalachiensis" is regarded as a separate species. I have thus corrected that in the text of my thread.

These two specimens were purchased by me. I was happy the original owner did a good job preparing them so that I wouldn't have to re-spread them; which it seems I do nearly (half) the time I get things from other collections !

Seems like (over here) too many people just don't TAKE THEIR TIME in working up their specimens; it's like quick, quick, and on to the next one. Things look hastily done and even sloppy to me --- literally at least 50% of the time ! Perhaps, many people simply lack the skill set (which I see as something of an art form) when properly done by someone who genuinely cares !!

Anyone...know more about black forms of P. appalachiensis?... rarity?
