Reecer Creek - June 26

On Sunday, I took my family up Reecer Creek for my first real butterfly-outing in the northwest this year.  The weather was great, no wind, clear, and temperatures ranging from 68 to 74 (according to my car anyway!).  This spring seemed to be just as wet as last year, but was a bit warmer.  I was happy to tally a good list of butterfly species and abundance, as well as observe most of the flowers seemingly blooming "on time".  Thanks to my mom for writing the list as I called out names and numbers from across streams and meadows!
