often observe monarchs roosting on the same trees — and even the
same branches — from one night to the next. Here is how one woman
described what she saw:
the hundreds of trees in our yard, the monarchs consistently manage
to find the very same tree--AND the same branch--on which the monarchs
roosted on nights before. At first I thought it was just chance, but
as the incoming butterflies select the same places night after night,
I really wonder if the others leave a trail of some sort."
attracts monarchs to a roost? How could you find out?
