One thing I've noticed since my traps seem to be a magnet for these red-spotted purples is the widely varying sizes of this lep. I get some that are not much larger than a question mark, then others close to swallowtail size. Is this size difference due to the sex? I don't recall reading about such a large size difference in this lep.

Females are noticeably larger than males.

Limenitis as a whole vary greatly in size. Females can be exceptionally large while males can be noticeably small. This is especially true east of the Great Plains. In the western half of Pennsylvania, Limenitis arthemis arthemis are all about the same size, males and females. However, the White bands very from full on both wings to almost absent.
While living in Augusta County, Virginia, both males and females could be enormous. And 50 miles to the northwest in Highland County, they could be almost tinny.
However, whenever I reared them, they were always average size, no great big ones, no little ones.
My opinion, larval host plant and the nutritional value of the plant. Just my opinion. And as we all know, opinions are like rectal orifices, everybody has one.
Over the years I have managed to accumulate seven drawers of Limenitis astyanax/arthemis from about every state east of the Mississippi River.
Should any of you live in an area with both species, L. astyanax and/or L. arthemis, set out bait traps and start collecting. You will be stunned at the variation.

Here in Southern Ontario we have both L.a. arthemis and astyanax. They are all rather medium size with occasional smaller male. Strangely I didn’t find so far some extreme aberration specimens of both, either way is one or the other.

With my 3 traps this summer, I seem to get more of this species than any others. I must have collected a couple of dozen so far, and that's only been just the last few weeks. Leroy, yes, I've noticed differences in banding. I've also noticed differences in the fluorescent wing colors. I have seen blue of course, but also green and sort of a violet too. Interesting lep. I only wish before it got too cold that the Limenitis archippus I see occasionally near my feeders would take the bait. It seems to hover around them, but not fly in. One day it did, but it got away before I could close the slots. I do have one in my display globe that I found in my bait trap three years ago, but it is a lot smaller than the one I have been seeing lately.

I just moved into my new home in Aurora, Ohio. Once I get settled and my collection organized, I will post some photographs of my Limenitis astyanax/arthemis drawers. I think I have five or six drawers.
I attempted to rear Limenitis astyanax astyanax more the once. All I managed to do was to rear a bunch of average size adults. I have had better luck with Limenitis arthemis arthemis and Limenitis arthemis astyanax(??) from Northen Lower Peninsula of Michgan.
Some of you should try rearing them.

My big rearing attempt was last summer: Papilio glaucus. I purchased small willow trees and placed them in an enclosure along with females hoping some would lay eggs. I also had small Buddleia for feeding. Despite all efforts, the females I would place in the enclosure would "play dead" long enough that I really thought they were and release them. I tried keeping them in the dark for a couple of days, hand feeding them, etc, but nothing worked. Later, I found out that I was using the wrong type of tree and should have used black or choke cherry. No time to try again this year, although there were many, many more possible candidates available this summer due to much better rain and no late freezes unlike the prior year.
I'd love to see your photos of Limenitis astyanax/arthemis. I've collected so many just within the last month with the three traps that I just had to freeze them until I have more time for pinning. I can keep them moist at room temperature with a lysol soaked paper towel inside the container, but for some reason if I don't watch, the lysol loses its strength and mold forms. So, if I go that route, I have to replace the lysol paper towels daily. Easier to just freeze if I don't have time to monitor.

Wild caught P. glaucus don't adapt well to a flight cage (even a quite large one), it would probably be better to sleeve them on the food plant and give them a daily feed of artificial nectar (I use 10% honey solution for my Papilios). Usually they will lay eggs if they are in contact with the host plant.
If they hatch from the pupa in the cage they adapt much more quickly, so perhaps the alternative would be to obtain some pupae and hatch them in the cage. You may have to hand pair them if the males won't behave, but you will have more success than by catching wild females and putting them in the cage.
Adam.
