8 p.m., close to sunset. Over 20 monarchs counted while roosting in various groups of 6-7 butterflies at the Pine Bend SNA. Some roosts were about 20 feet off the ground in white birch trees, some roosts were roughly 30-40 feet off the ground in massive cottonwood trees, and some were 15-20 feet off the ground in basswood trees. No monarchs observed roosting in the many oak trees nearby. No monarchs were on the liatris aspera, which has almost completely fallen to the ground under its own weight. The photo shows a birch tree roost.
