I still have some bear spray from a trip I made to the Yukon a few years back, be assured I'll be taking it with me. Are there many mosquitoes in the area? Be sure to check the bear spray expiration date. I bought some when I was in Glacier NP some years ago, and it was specifically stated that it doesn't last very long. I seem to remember a year, but it may be more.

I can't think of any reason why a pepper spray should need an expiry date, surely pepper isn't going to go off. They're not cheap either - this one cost me $45.

I have been assured that both curius and eurous are definitely nouns. Certainly Curius is the name of several ancient Romans, see www.attalus.org/names/c/curius.htmlAdam. PS. I agree they can also be adjectives.

Out of curiosity, I just did a search for "bear spray expiration". It got a lot of hits; one of the prominent ones says that their brand has a 3-year expiration. They say that it doesn't become useless, but loses strength as it ages. I don't have mine anymore to check the date, as I didn't expect to venture back into grizzly country anytime in the near future

The liquid will be always inside the can, but it will lose the pressure with time and will be come useless . Also if you would make a noise when you walk the bears will walk away.... and butterflies too

Colias specimens collected in Alberta near Banff. Colias philodice philodice Colias christina christina Colias alexandra alexandra PS. Bob as you are a specialist on Colias group if any identification is incorrect please reply. Paul

The philodice and christina are correctly identified. The third one cannot be pelidne as it doesn't occur in this area. Some of these yellow Colias are difficult to identify, could you let me know when it was collected and what is its wingspan relative to the christina specimen?

Hi Bob According to the book "butterflies of canada" There is a population in Alberta - Rockie Mountains www.cbif.gc.ca/eng/species-bank/butterflies-of-canada/pelidne-sulphur/?id=1370403265727However I was not sure at the first place about that identification . It is same size as C.christina and I collected it at about 1300m. In the book there is only a picture from Labrador population and it looks a bit smaller, but perhaps western population could be larger. Indeed it is not easy to correctly identify them as they look alike. Paul

The website says that the Rocky Mountains populations are C. pelidne skinneri which is correct, although I regard C. skinneri as a good species. The Canadian populations are C. skinneri minisni if this is indeed different to the nominotypical US populations. C. pelidne is most commonly found in Labrador, with scattered populations across the rest of arctic Canada.
However, your third specimen is not C. skinneri, it is too big, the wing shape is too pointed and the underside pattern is wrong. I would say it is another specimen of C. christina with far less orange than your other specimen. The only other possibility is C. alexandra although I'm not aware of any populations in this region.

I guess it is really difficult to positive identification . Again as per book there is a population of C. alexandra in Rockie mountains national park in Alberta , so it is possible that what it is. I don't think it is C.christina as the dots are totally different on my specimen unless there is variation ...

The revue Lambillionea with Joseph Verhulst as author will soon publish a special volume of aberations, gynandro and strange specimens of Colias ! probably end of the year.

All Colias species are very variable and there are several very similar yellow species found in the Rockies, this is what makes identification of these so very difficult. I have checked my records and you are right that there do appear to be some alexandra populations in this part of the Rockies. Judging by the phenotype your third specimen is therefore almost certainly C. alexandra.

Thanks Bob Good luck on your trip to Canadian Rockies. Let us know what you will find there . I am planing to go there again next year July in hope of finding Parnassius smintheus and perhaps some new Colias.

Talking about Colias beauties, this is a fresh female Colias phicomone that I have met in the French Alpes on Sunday, above Les Carroz, 1700m. A very unique species in Europe.
