Visually, where do we draw the line between hybrid trait vs range of variation? If we look at the specimen from Cochrane, there is no way that’s a hybrid given the location. But the lunules on the hindwing underside are far from rectangular which is what you want to see for canadensis. The shape of the lunules are a good indicator for canadensis vs glaucus/hybrid, but for me, the most reliable/consist traits are the black band on the HW anal margin and the submarginal yellow band on the FW underside.

For the western Canada specimens, I'd have to see the verso on most as well; some seem to be perhaps hybrids as well.

New York specimens upperside
New York specimens underside
other canadensis
If Chuck needs better quality photos of any of these please let me know. I assume that the specimens in the 3rd photo are all canadensis, but was surprised that one is from South Dakota. As for the New York specimens, the one on the right is somewhat larger than the others, but perhaps these are all not true canadensis at all.

A fellow collector and friend went to Ecuador in 2004 for a week. He was there to do a particular job but, at night he set up a light where he was staying and would do his collecting. He only had 2 killing jars with him and was using ethyl acetate as a knockdown agent.
After he initially stunned something using the killing bottle he would then transfer the specimen to a large round "christmas cookie" tin which he had poured plaster of Paris in. He would use this as his "dump" container for his killing bottles so he could keep the process of capturing things moving along.
When his week there was done he packed up his gear and headed back to the US via Miami airport. Upon his arrival he went through customs. He had placed this cookie tin in his carry-on luggage. It was x-rayed. The cookie tin came up as an object in question.
One of the officers took the cookie tin out of the carry-on bag and asked what was in it. My friend replied nothing. While this was true the officer started pulling on the lid to open it and my friend said "I WOULDN'T OPEN THAT IF I WERE YOU" !
Well, the officer looked at him popped open the lid and got a face full of ethyl acetate odor. The officer immediately drew his gun and pushed the panic button which sent everyone else (near my friend) scattering with my friend standing there at the x-ray belt.
He said in like 1 minute he was surrounded by 6 officers all pointing guns at him and screaming at him to get down on his knees. He was handcuffed and taken away and wound up having to do a whole lot of explaining.
Charges were filed against him and he wound up paying a sizable fine of some sort which to this day he is never revealed to me. It was a very painful lesson learned by him for an oversight.
I suppose logic would have made most of us leave that container and the killing bottles back in Ecuador. But, again not everyone shares the same thoughts.
Better to be safe and leave equipment behind (if you can) so that you never have to go through the experience my friend did.

Thanks, i see that Thymol in crystals is available in most African countries, so will go that path.

I have always travelled the world with my cyanide jar and never had any question/issue. Once in Japan, they checked it, and I said it was to kill mosquitoes. They were very happy with that answer.
Have a nice trip !

Travelling with Naphalene and Chlorocresol through airports
by Annarobertson1947 » Sat Jun 01, 2024 8:50 am
I'm travelling to Sth Africa, Zambia and Kenya early next year, taking a store box and wanting to take a small supply of napthalene and chlorocresol as mould preventer as its a trip through high humidity.
Am i likely to encounter issues over possession of a small bottle of white crystals,??
Customs can get a bit aggro.

I should note that though these are my field notes, I am not working alone, and am indebted to others.adamcotton wrote: ↑Wed May 29, 2024 5:45 pm I must say Chuck is doing a great job trying to unravel what seems to be a very complex situation.
Adam.
Eurytides, who got me started on this darned project to begin with, continues his research in Canada and is my constant email companion. I lean heavily on him for learning and as a sounding board.
Jshuey has, behind the scenes, given me invaluable "off the record" advice.
Jhyatt, and others, have provided regional voucher specimens for comparative studies.
Images and observations from 58chevy, mothman, and Paul have helped define ranges, flight period, and behavior.
Bob gave me access again to the Carnegie collection (itself a must-see snapshot of entomology 100 years ago). The team at Cornell as well.
Adam, you as well on taxonomy and genetics.
There's a lot of back-and-forth question/answer sessions via email and PM. This helps educate me on systematics, taxonomy, Lepidoptera politics, and genetics.
So even though what most people read is my daily field report, there are actually a lot of hands in this research pie.

63F/ 17C
50% cloud, winds NW 15
Observed 8, captured 0
OK, this is rediculous. I've started building my decoy, which I had 9 months to make, but didn't.
