Coordinator notes: Christian, I'm scanning my pending sightings for unusual things....as you have posted several that wait verification, I will get to those but may be awhile (I did several a couple days ago). This one caught my eye because it is rare to find pawlowskii in the ODD YEAR. It is normally found in even numbered years but a few have been observed or collected in odd years. Try the site again next year and see if you don't see more than just one. The populations in Gilpin-Boulder County are intermediate between the San Juan Mts. demmia and Wyoming ethela although my opinion is they are close to demmia. You'll read about that in my book when finished. Mike
