With Fritillaries spread across the northern hemisphere, has there every been a study to determine where they developed and how they spread across the continents?

Thanks Adam. I thought about using Childrena but thought it was now back in Argynnis. My mistake.

An interesting 3 yr. old video depicting the complete life cycle of this magnificent butterfly:

Another 4 yr. old video on a Homerus Genetics project; both videos are by the same researchers:

Fabulous! One of the most eye-catching fritillaries I've seen.

Gotta' love those bluish outer margins !

Bet they really "Pop" on a sunlit day and against
that rich orange color. Wonderful....

Back in the day (late 1970's, early 1980's) this used to be a readily available species for collectors at least here in the U.K. with most (if not all) specimens coming from India. It was one of the first tropical species I owned
I have an Indian pair in my collection which is over one hundred years old. No pictures of that pair currently. They are still in reasonable condition.
Common names are Himalayan Fritillary/ Large Silver Stripe.
This pair shown upper & underside are from
Viet-Nam

Thank you eurytides for that explanation.
I never really gave it much thought; I only noticed
that some males were "somewhat" diffrent looking
than the greater number that I have encountered.

Finally got into ChatGTP AI. I asked it to differentiate between ssp of Ornithoptera victoriae. Among the ssp it gave me was aesacus and hauseni, as well as victoriae and regis. It did not cite other ssp.

I asked it a different question, a tough question, and it totally failed.

The nanoscale structures on the scales will have some variation, just like everything else. If the structures are off by a few 10s of nanometers, you will see a slightly different color (caused by interference of light rather than reflection or absorption).

Thanks for sharing those John. Really beautiful abberations.All of them !!

Trehopr1 · by Trehopr1 » Tue Mar 21, 2023 8:46 pm

Those are pretty awesome (natural) abbs. that you have managed John. I've never seen anything like them naturally occurring.

Mighty special finds indeed....

Well if Papilio glaucus can sustain morphological changes due to genetic alteration from the environment, and these changes are inheritable, I'd think the same would be quite possible with other Leps. That would explain the temporal difference in the same location.

I'd go back and look for more.

Here is a nearly identical "hygiaea" variation, to my #6 example above, that I believe was also posted to my original specimens post years ago. It was from Nobles County, Minnesota - 14 July, 1986.

Mourning Cloak (Nymphalis antiopa) ab. "hygiaea" (interesting variations) - Following are 7 examples of this rare ab. that I collected, in the wild, a number of years ago, & were originally posted on Clark's "insectnet" site. These are now artificially reproduced by chilling the chrysalises, but wild collected specimens are still quite rare. As far as I know these are the only known specimens from Saskatchewan, CANADA. I would love to hear (& please show us here) of other wild collected (ONLY!) examples from N. Am.. These specimens are labeled from #1-7; #1 & #2 were collected the same day in early August; #3-7 were collected, in very late August, 3 years later, on 2 consecutive days, & on the same 7-8 mile stretch of backroad !

This lovely butterfly is one I have posted about before in the past.
My discussion was more focused on the 2 color forms which the
males exhibit.

Below, are the two forms with the top one appearing as a "shimmering"
blue whilst the lower one is more of a "gun metal" bluish-green color.
These are NOT a play on light or camera angle !

They are as they appear in my photo.

I've never read that paper. So wonderfully written, you're a man of many talents. Thanks for sharing the link.

You are too kind Chuck. I am glad you enjoyed reading it. I was told by one of the reviewers this was the most detailed discussion of philenor they have ever read.
