Obs. made from 12:30 to 4:30 p.m. Partly Cloudy and 79-81 degrees. Diversity low. We did not explore the wildflower meadow today, only the formal gardens. Appears to be a northward push of Sachems right now possibly linked with last week’s tropical storm. We had one additional butterfly, a sulphur species that escaped identification.
