On a serious note. I have collected several white form females on my property. Until I moved here I can't ever recall seeing any. Their distribution seems to be localized.

It is on a spreading as of 4:30PM today 18 September 2016. She laid about 40 eggs, all were very light blue (Typical). She was dead in the cage this AM.
She very beat up, but she is on a spreading broad now.

Can't wait to see it. Even though it's damaged one of that size is definitely worth keeping

I remover my large female Colias eurytheme from the spreading board this AM. I place typical size specimens which are still on the wing. She is rather worn after being enclosed in a cage with a pot of Alfalfa.
She laid a total of 38 eggs. 22 emerged, the others turned black and evidently not viable. The larvae are currently in the last instar and should pupate in the next day or two. All of the larva were normal size. I am making the assumption she was just a size variation and nothing more.
As you can see, she is much larger than typical adults. It is the largest Colias I have ever seen or collected. She is rather wing worn after confinement in the cage. The wing tips are slightly diminished from contact with the screen of the cage. |

I got this neat colias a coupe weeks ago. I would say that it is probably a philodice. Here it is next to a regular C. philodice female.  P.S. sorry for the bad quality photo |

Yes, they are cold weather (Fall = Late Sep or early Oct) forms of Colias philodice. Did you get any white females with lot's of gray/black/green on the Dorsal hindwings?

The Colias philodice on the Right, the larva feed on Alfalfa. And as the result of the diminishing day light hours is has that "Fall" look. The Individual below is from Grand Isle, Vermont and collected on 8 October 2008. This is a stunning specimen which was chilled as a larvae and as a pupa. May have experienced an early frost. The colors are amazing.  Colias eurytheme and Colias philodice can produce some amazing adults due to host plant and weather conditions. We have experienced are first cold snap last night, 44 degrees and tonight it will dip into the mid-30's. A warming up is coming over the weekend and I will be in some clover fields next week with net in hand looking for strange looking Colias specimens. |

I have never been able to cross Colias philodice with Colias eurytheme. I have attempted hand pairing a number of times and they never produced viable ova. I have collected lots of odd looking specimens. But when you "look" at them, they are easily separated.
I just went and looked in my collection, I have six drawers of Colias eurytheme and five drawers of Colias philodice. Plus a drawer of white females which contain both species that were reared.
To answer your question, have I ever collected a hybrid, No.
By the way, the temperature in my yard this AM was 39 degrees. Most of the larva in my cages have disappeared into the leaf litter in the pots of the host plants. All of the adults are at the top of the cages pointing east looking for the rising sun.
