Monarch Chair

Monarch Chair
Why does the Monarch butterfly come to rest in the same spot in my garden,(right in the middle of the lawn),?

I see a monarch butterfly every day at the same spot in the back yard…..If there is a lawn chair in that spot it sits on the lawn chair, if someone is sitting on the lawn chair the butterfly sits on that peron shoulder….if no lawn chair it sits on the grass of the same spot….I,m baffled, anyone know why

it has become a favorite spot to rest and get a bit of sun in between feeding during the day.
