Maybe occidentalis and nelsoni are conspecific. Maybe they are not conspecific. It is an open question for me. Here is link to a distribution map that I have found interesting since it was published i

Thanks so much, Jason! I'm glad to hear it--makes it all worthwhile. Yeah, it's hard to curl up with a personal device in the back of the camper or tent on the cold, rainy tundra. I'll never forget cu

This morning I noticed that Heiner Ziegler had uploaded pics of some Pieris angelika paratypes to iNaturalist. These modern digital images are much better than the old printed-on-paper images in the o

An iNat record prompted me to share an old but useful pocket camera pic comparing eurytheme and philodice from southern British Columbia. From my butterfly discussions with many people over the past 5

Hi all, I thought it may be getting late for this topic, but our new blanket of snow in the PNW has reminded me that winter isn't over and the butterflies are still using mysterious tricks to survive

I have uploaded to flickr the last two of the grandis graphics I have made recently. One northern British Columbia: https://flic.kr/p/2oimgbj And one for the isolated population in the Cypress Hills o
