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

Sunday, September 15, overcast until around 3 pm. Humid. Wind SW approximately 5-15. Around 5 pm winds calm and seemed like a slight north shift of the wind. Even this very slight shift had monarchs changing locations and setting up on south side of trees.

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

Roosts set up on south sides of walnuts and maples in lowest point of yard. When I checked roosts on Monday, September 16 at 715 a.m. I located approximately 200. Clusters were smaller today with quite a few consisting of approximately 20-30 butterflies being the largest. Lots of small clusters of 2-10 and many singles. Butterflies were scattered throughout many trees. Temps were 62 and sunny with fog.
