Number: 500

On Monday, the 14th my husband startled a large number of monarchs (approximately 200) in a grove of trees. We have been observing them in the area which consists of a large field (25 acres) of clover surrounded by timber. There are hundreds of them in the trees in this area and they are getting nectar from the red clover blossoms in the field. It is impossible to count them since it is such a large area but we took pictures and on one I counted 37 in a 5 foot space of timber. It seems like their number has increased from the first day. Reported 9/17.

Editor’s note: Observer confirmed 9/14 is the night the roost formed.
