What do you call a group of butterflies?

Question

I would really appreciate it if you guys could write your sources too. Thanks!

Answer 1

Called a kaleidoscope.  Or swarm.  Or even a rabble.  I got this from <amazingbutterflystore.com>  I feel that an old name they had a hundred or two hundred years ago should be what they are called now, which was a flutterby.

Answer 2

According to the NABA there isn't one specific one that is used. However, I have seen and heard "flutter" of butterflies used quite a lot.

Answer 3

a swarm?  I think a swarm applies to any insect.

Answer 4

flight, kaleidoscope, rabble, swarm.

Answer 5

both- a swarm and a rabble
