Monarchs have been roosting in my yard every night since September 1.

Wednesday, September 18, sunny in morning, scattered clouds. Humid. High temps mid 80s. Wind S approximately 5-15. 3:30 pm clouds roll in and storms with heavy rain and strong west winds by 4 pm. Temperature drops quickly to upper 60s. Rain over by 5 pm and winds calm. More rain possible overnight and Thursday a.m.

Lots of nectaring going on Wednesday. Still predominantly nectaring on zinnias, tithonia, etc. Again today, noticed early roosting at 3 pm on north side of maples and walnuts at lowest point in yard. Easily startled at this time of day. Many still nectaring at this time.
