My book with Robert Michael Pyle is now out! ...I know, I'm a bit late in posting this...it came out last month and has caused a flurry of activity in my trying to distribute complimentary copies to all the photographers and answering many dozens of emails. We've been pleased and humbled by the enthusiastic response it has had so far.
You may find it at major retailers and many local bookstores. It's a great resource covering all butterfly species in Washington, Oregon, and surrounding edges of British Columbia, Idaho and California, if I do say so myself :)
Also, don't forget to check out my own website where I'm selling my two self-published books: northwestbutterflies.com
