Re: New Papilio paper

Nevermind. I just downloaded the paper and realize that both Julian Dupuis and his former PhD supervisor Felix Sperling are authors on this paper. I'm not completely surprised to be honest. Dr. Sperling is a giant in the field.

Re: New Papilio paper

Regarding Papilio kahli, Julian Dupuis has done a lot of molecular work on the machaon/polyxenes group here in North America. It is of hybrid origin and Dupuis et al places it under Papilio machaon kahli. https://journals.plos.org/plosone/article/file?id=10.1371/journal.pone.0141882&type=printab...

Re: Does anyone the whereabouts of Henry Hensel from Edmundston?

He was still active as of 2021. Email John Klymko, a zoologist at the ACCDC. They have often collaborated in the past and he should have more up to date info on Henry.

Re: Battus philenor

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).

Re: Battus philenor

I have enjoyed raising this species in the past. I wrote a monograph for the Toronto Ento Association about a decade ago. https://www.ontarioinsects.org/publications/PipevineSwallowtail.pdf I've never read that paper. So wonderfully written, you're a man of many talents. Thanks for sharing the link...

Re: P. glaucus (transitional) "smokey" tiger (female)

Well, “normal variation” is a subjective term. Just how common does something have to be for it to be considered normal? I have no idea. However, I have never seen a smokey tiger in real life, so that seems rare enough. Bleeding colors or slightly scalloped tiger stripes - half my specimens have som...

Re: P. glaucus (transitional) "smokey" tiger (female)

I have read this paper as well. Some of what they called “aberrant” are probably what most of us just call normal variation. If you look very closely, a significant percentage of specimens will have some amount of aberrancy based on their criteria.

Re: Papilio weymeri

The label says P. cartereti, which is a syn of weymeri. Unfortunately it's the other way round. Meanwhile, everyone uses Papilio weymeri , so let's continue using that for now. This will be published some time in future among other nomenclatural issues in Papilionidae. Adam. Thanks Adam. I was uncl...

This is also an excellent website and basically continues the work by Tuttle et al. I have this book and agree it is superb. Used copies are about $100.

I will throw mine into the mix. Here are some canadensis and glaucus. Aberrant female 2nd row 4th specimen. Aberrant male lacking black anal margin on HW bottom left corner.

Re: Papilio glaucus (natural occurring genetic anomalies)

Appalachiensis is about 3/4 canadensis. So for example, the black anal margin on the hindwing is much thicker, closer to canadensis than glaucus. But like Chuck said, most of the pertinent characteristics are better seen on the ventral side.

Re: Interesting character - Eye Popping Collection

I have seen some of his videos too. I think most people only spend a few minutes spreading a specimen. Sometimes, that’s out of necessity because of the sheer volume of specimens one has to deal with. I only add a few specimens a year to my collection because they are essentially all reared. And sin...

Re: What's up with US Saturniidae?

I was in contact will Bill last year. He seemed as active as ever. He has a supplier network in Canada and the USA but doesn’t ship across the border for obvious reasons. Give him a shout. I have a bunch of cecropia and promethea cocoons in the garage but I believe you are in the US?
