Porcupines, monarch butterfly and bats

There was a family of porcupines near our cabin, eating twigs and plants on Thursday night (around midnight).  We saw a young one climbing up a tree.  I also saw a Monarch Butterfly in our garden fluttering around the milkweeds.  I hope she lays eggs in a milkweed.  We were seating in our porch Friday night and we finally saw three bats fly above us.  I was so happy to see them, since their population has declined in past years due to the white nose fungus/disease.
