Coordinator notes: On the eastern slope in the Front Range we have Speyeria callippe meadii (on the western slope is ssp. harmonia)....typical meadii has a fully green (fairly dark green at that) ventral hindwing disc but you get variation that includes a light submarginal area that is typical to harmonia in the western counties as on your photographed individual. If you collect a series of these, you will see the range in this variation quite easily. In Larimer County, there is some Great Basin influence in some other species there but this variation in callippe extends south along the Front Range also. My favorite place to collect is Young Gulch in Poudre Canyon (just east of Mishawaka). Can you access it or not....someone told me it was closed due to rockslide or something but that was a while ago)? That is a great place (just watch out for the rattlesnakes - some don't buzz and are totally docile). You might get lucky and get one of those really green disc Speyeria coronis....Great Basin influence that produces an occasional green disc synderi variants of coronis halycone and also blends of brown and green. Really neat bugs. Let me know if Young Gulch is open.....and now is the time to go to check it out. Mike
