I am reluctant to post Photographs of my drawers. I posted several drawers of my Tiger Swallowtails which resulted in several emails about being a show off. Really? that is a nonsense. The more pictures the better, forum is more interesting. |

The more pictures the better, forum is more interesting. Agreed, I'm a long way from posting pictures, I don't want to appear an amateur... Nice pictures though, I like the sulphurs, I don't see them often, and it's always an effort to catch one, one of the few I'll pull over for. |

Hey mikeh, I don't wish to be a bother but, could you post us a close up of those C. nastes from Canada. The male is partially obscured in the photo and he really looks to be very unique. I am unfamiliar with the species so any close-up's would be most appreciated. Also, what is the frequency by which you encounter those "white" females of C. gigantea ? Is it 50% of the time ? Maybe less ? Some populations have all yellow females, some have all white and some are mixed, where they are mixed either one can predominate.I also noticed that some of the females appear very "light" in yellow coloration as if there is a "transitional" phase (?) or form (?) present in the species. Perhaps, bobw can tell us what is going on here with the species as he is the resident expert on Colias butterflies... Mixed populations will have some intermediate forms.Thanks again ! |

Another question mikeh regarding C. interior. I noticed you only have 7 females in your lovely series. Are they less frequently encountered for some reason ? Do they have a different flight time or emergence cycle than males ? Like most butterflies, the female's flight period usually starts a few days later than the male's, and finishes a bit later. Males are always much more visible than females as they fly more, looking for females; females usually just hang around the foodplant and don't fly as much. Although if you're very early in the season you'll find more males and late in the season you'll find more females. Females are always less frequently encountered due to the lack of visibility.You also have a singular albino female. How tough are those to come by ? White females of interior are very rare except in one or two populations, notably that from Seeley Lake, Montana where they could reach about one in 20.Sorry for being so inquisitive but, I've always liked Colias in general and these western species are intriguing... |

I have about 25 drawers of North American Colias, representing various different populations of most species. If there are any species anyone particularly wants me to post, just ask and I'll see what I can do.

Thank you very much indeed bobw for kindly answering all my many
Colias questions ! Your knowledge of these butterflies is very impressive.
Wow, you have a "whopper" of a collection of N. American Colias...
.
I suppose like mikeh you too have been to many beautiful locations here
in America's western states collecting all these different species. Sounds exhilarating
and most memorable.
Funny, how I have lived East of the Mississippi all my life but, have traveled so little
west of that great river dividing the U.S.
Never enough time, money, or freedom in life to have done so...
Sadly, I've probably seen more beautiful country shown on the television program "Yellowstone"
(starring Kevin Kostner); then I have ever experienced in real life !
A lot of great places and spaces out west indeed. Thanks again...

Unfortunately, I've made fewer trips to North America than I would have liked. I've been to Alaska twice, arctic Canada once and three times to the Rockies, travelling between Utah and BC. Obviously I've tried to maximise my time there, getting to as many sites for Colias as possible in the time available. Also, I've bought and exchanged many things that I couldn't catch myself.

I am unfamiliar with the species so any close-up's would be most appreciated. Here is a close up of the nastes  The top 2 are from Alberta and bottom 2 are from Alaska. Neither were self collected, I have never collected in Alaska, Canada, the Pacific Northwest north of Lake Tahoe or East of the Black Hills, but everything else was self collected other than the behrii and most of the Arizona material. |

Fantastic photo mikeh !
Thank you for indulging my interest in this lovely
group of butterflies. Certainly a notable colias species for
it's unusual green coloration.
The info was also interesting...
