Adam Would you please change this thread to : Colour variation in Colias We could all share all different species of this genus here. That is of course if trehopr1 wouldn’t mind. Paul I changed the thread subject as requested. Adam.

For my "Grand finale" this late evening I offer viewers a glimpse of my "special stock" or best captures of the last 5 years running. All have been field captured by me and represent the careful selection/capture of the "boldest" examples which I have encountered... These are all Colias eurytheme. First 3 columns (males), Second 3 columns (yellow form/females), Last column (albino form/females). These are all happenstance captures as I don't necessarily focus on them whilst in the field. I have personally prepared, labelled, and curated all these specimens myself. A labor of love. Took some time but, I feel it was well worth it. I have about as many nice ones of older captured stock as well (which I will muster together later this year); problem is the cost of good Cornell drawers keeps rising and I can only afford 1 or 2 at a "pop" before taking a break to catch my breath financially.

I only collected few of Colias eurytheme and I should perhaps pick up some more this summer. Orange female is rather rich dark orange. Top male (second picture ) was collected in Alberta and resemble C.christina and at this point I am not sure if actually it is C.eurytheme.

Trehopr1 your drawer of C.eurytheme should be an example how drawers should look like, wonderful work! Makes me want to collect more Colias this summer!

Nice indeed cabintom ! Thank you for your input to this thread. As always, love the presentation of your specimens and admire your photography skills....
Paul, thank you for your kind regards ! Perhaps, both of those Colias species above overlap somewhat in their broods (at some point in the summer). Therefore, you may find both... Or maybe, there are hybrids of both species present. Just food for thought.

To any fans of Colias out there I am resurrecting an old post from the other forum which a member at the time "brought to light" of a hitherto very rarely seen aberration of our Common Sulphur (Colias philodice). At the time, the member referred to it as a "form" but, was corrected by our resident Colias expert Bobw in a later post. Another member also remarked that he too had collected a similar specimen on only one occasion... Below, is the original post. Also, below is an enlargement of the posted specimen. One could say that finding one of these extraordinary males is akin to finding the mythical "white buffalo" amongst an endless sea of black buffalo's on the plains of the Western U.S.(circa mid-late 1800's). So, needless to say whenever I happen upon a "white" butterfly of any kind within proximity; I make it a point to give them all a thorough look ! White males are indeed very rare. The only other one I've seen was a white male of C. thisoa which an Italian dealer had for several years at the insect shows in Europe. The reason he had it for several years is that he wanted a crazy price for it. Interestingly, there used to be several white males of C. hecla from Sweden in Jan Haugum's collection (now in Copenhagen). These were recovered from pitfall traps set for terrestrial Coleoptera, and having been in there for several weeks had become bleached by the chemicals used therein!

Paul
In your post on the 20th with the christina you say that the left column are males and the right females, but the top specimen in the left column is a female, I assume you're aware of that.
In your post yesterday with the eurytheme you say you are not sure whether the top male collected in Alberta may be christina. Check the underside - eurytheme should have submarginal black or brown spots on the hindwing underside, in christina these are missing.
Bob

Thank you Bob Yes, it is female and somehow end up with males. I confirm that it is C.eurytheme, I did identify it correctly few years ago but forget the key to separate the two, thank you for reminder.

Hi Trehopr & other American Collectors, NOW... is the time to buy Cornell drawers from a good Canadian supplier: www.atelierjeanpaquet.com/en/shop/cornell-drawers/Our Canadian dollar is currently severely devalued: at today's rates (xe.com) 1 USD = 1.45 CAD... therefore Atelier's best Cornell drawers (varnished, plastazote foam, 1 drawer pull, 2 card holders) at $37.00 CAD = only $25.00 USD EACH!! At such prices (compare to BIOQUIPS!), even with shipping costs to the USA.... should still be a bargin. I have used Atelier's Cornell Drawers/cabinets for about 10 yrs. now & like them a lot.... have not had a single dermestid beetle infestation with them. Please note I have absolutely no business association with his company & this is only a suggestion... gotta take advantage of such deals! Wish the situation was reversed! John K.

Thank you very much boghaunter on the update regarding the cost on those Cornell drawers. I know I will look into the matter. Very much appreciated...
I believe you were the one who originally responded to bicaliber's post regarding his capture of a white (male) C.philodice. In that post, you mentioned that you caught one as well. If you still have that specimen do you think we could all have a good look at it with a photograph?

I can also vouch for these drawers. They are top quality. I think they are the best bang for your buck. Shipping is very expensive but with that cost per drawer it is still the best I have found around. Also, thanks for alerting me of the current exchange rate. I may be buying some drawers quite soon...

Hi Trehopr1,
Great Memory Trehopr1... Yes, indeed you are correct... I did collect a nearly identical, white, male, C. philodice, in the month of May, about 10 yrs. ago. I still haven't sat down & taken the time to figure out how to post photos here yet... Suffice it to say my specimen appears identical to BicBug's, except it is slightly smaller & more worn. My specimen is definitely white in colour though (not worn enough to rub off the white scaling). My original photo of my specimen was posted right after BicBug's & the webmaster can post it as well from the old forum. Too bad all the wonderful posts/photos from the old forums can't be downloaded to CD's or memory sticks & offered for sale to current members... I would be happy to pay $$ for them… a chance to raise some badly needed money for this site & it's sister site as well??
Hi Mothman27,
Yesterday, after posting my original alert for cheap Cornell drawers, the Quebec gov't.shut down all non-essential businesses due to the Coronavirus. Perhaps one can, presently, by email/phone, still order & prepay for them, thereby still taking advantage of the advantageous exchange rate. Just a note... when I ordered 24 drawers a few yrs. ago... I wanted the premium drawers described above, but in chocolate brown instead (I don't care for the common, plain, blonde, varnished ones... I like the deep, dark brown colours of the old traditional "Victorian" style drawers/cabinets). It cost a couple bucks more for each drawer, but I was very happy with the results... a custom order will take time... I waited about 6 wks. for my order... & now with Coronavirus... who knows?? P.S. - Atelier's inside walls of his premium drawers are also painted white (just like BioQuips!). Good Luck!
John K.
