My daughter had taken caterpillars from the sweet fennel in her yard; and has them on a bunch of this in a vase. One individual left the room, climbed the stairs and formed it's crysalid on a chair in her bedroom.

Spent her first full day in and out of the yard; returning repeated to these plants.
