Here's a photo of the undersides of the other canadensis:

I'd say all NY specimens except the specimen from Green County are "mostly canadensis" though all show some intermediary (hybrid) traits. The very thick black line along the abdomen is thicker than Spring Form, MST, or glaucus, which infers primarily canadensis. That said, the HW verso lunules on most are not so nicely rectangular as on nominate canadensis. Greene County I suspect has a high percentage of MST or glaucus.

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

Most all collected in bright sunshine by hand feeding among arrowood flowers. Here are three other species I also collect on arrowood flowers here at my home around the same time each year. Trichiotinus piger (Fabricius), Cotinis nitida (Linnaeus), and Euphoria sepulcralis.

I take the view that white crystals of anthing nowadays going through airports is setting you up for trouble.
I dont trust customs to be reasonable

I looked at my spread supposed P. canadensis today and decided to upload photos here to contribute and also ask whether these are canadensis or something else:

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.

Exercise caution in anything you pack whenever you are traveling.

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.

Naphtalene in small quantity should be no issue at all. If they ask, say "moth balls" to kill insects in my bags. They will be more than happy to let you enter with that.

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 !

I'm going to throw this out for comments,
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.

It's been a long time since I've collected Hemileucas. I am sure they fly in some of our collecting areas, it's probably just timing. The last larva I
collected on wild rose was parasitized.

Make sure you get the looser weave bag. The tighter weave is too hard to see through and slows the net. You may have to ask for this via messaging or email.

Adam.

I should note that though these are my field notes, I am not working alone, and am indebted to others.

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.

OK, this is rediculous. I've started building my decoy, which I had 9 months to make, but didn't.

Do you ever collect any of the Hemileucas in Oregon Kevin? There are some really cool color forms of H. eglanterina, H. nuttalli, and H. hera in south/central OR.
