As we were backing out of our garage, we very briefly saw a Monarch Butterfly disappear around the northwest corner of our house heading south at about 15 feet above the ground.

At the time (~4:30 PM), the air temperature was 81°F, the dew point was 57°F, and the humidity was 45%.  The air was calm under partly cloudy skies with the air pressure at 28.75 inches.
