Number: 4000

The Monarchs were resting in a couple trees under a bridge on US 90. Thousands of them resting before heading further south to Mexico I assume.

This roost was early in the day (of 10/14/16). I'm not sure what time exactly as we were actually in the process of running the American Flag across the US. The butterflies were shielded from the wind under a bridge. The winds were pretty harsh at approx 15-20 mph out of the south. I am not sure of the actual date they first formed. I would have to say easy 2000-4000 maybe even more. I hope this helps. I have really enjoyed tracking the Monarchs. There were also a many other types -- or should I say colors -- of butterflies. But I know for sure the Monarchs were there. It's a shame so many are killed in the highways on their trek.

Editor's note: We've re-dated this report from 10/14 to 10/13, the night the roost formed.
