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

Gotta' love those bluish outer margins !

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

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

Nowadays this species is placed in its own genus, Childrena Hemming, 1943.

I edited the subject accordingly.

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

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?

Dave,

It seems you are right, and apologise for the error. I note that books used that name, however I have just seen that
http://yutaka.it-n.jp/hel/710080001.html
treats it as Argynnis childreni childreni Gray, 1831

As a result I will change the name back in the subject line after posting this.

Chuck asked an interesting question. I expect that there must have been, since it seems the species has been moved back to Argynnis and would appreciate hearing about them from someone who knows.

I found this, though it's 2019 and only on Speyeria. https://scholarlycommons.pacific.edu/cg ... t=uop_etds

Right up front they state they couldn't do a more comprehensive analysis due to lack of samples (specimens).

It would be interesting to know what other Nymphalid Speyeria and Argynnis are closest to; Euphydras maybe?

Interestingly Speyeria is treated as Argynnis by some websites. They are in Heliconinae subfamily so the closest would be Boloria as it is in the same Argynni tribe and then would be Heliconius and other.
Euphydras is in subfamily Nymphalinae

Thanks Paul! And zero effort on my part to look it up!

A really magnificent fritillary!

Have taken a picture of my old Indian specimens. The hand written data for the male is shown " Ranikhet 30-5-14"
1914 making this pair almost 119 years old.
