One of my favorite things at Meijer Garden.  (some of the photos are not very sharp...I was with 6 students; one of them is/was afraid of bugs and another doesn't like crowds...)

thousands of butterflies (and lots of people), in the main conservatory - 5 stories tall...

you can watch them come out of their cocoons...

enjoy their dinner...

and if you're lucky...land on your clothes (you shouldn't let them land on your skin, because the oil can harm their feet - and that is how they taste things)

This is one of the reasons I have an annual membership...so I can keep going back
