Papilio glaucus (Spring generation / transitionals)

Post by Trehopr1 »

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).

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 !!
