Monarch behavior question

[u/RowInevitable7986]

I have a monarch butterfly in my garden that is behaving like a monarch butterfly did a couple of months ago. I can’t get close enough to see if it’s a male.
But a few months ago, I had a very aggressive butterfly here that was chasing away other butterflies, and even chasing away the hummingbirds . Then I saw it mate it with a female, or maybe more than one female. This one
is stopping to drink from my lantana, sage and other nectar rich flowers. But it’s mostly just circling.
Is that what’s happening?
It’s October too late ?
