Butterflies do fart.
Even though butterflies don't eat solid food the butterfly does often swallow in air while eating foods which builds up as gas inside of them and then they need to fart.
However adult butterflies do not urinate or defecate (or "go to the bathroom").
The larval life stage - the caterpillar - does all of the eating, and caterpillars almost continually defecate.
Interestingly, when there enough caterpillars eating in the same place, their defecation is audible.
That is, you can hear the poop!
Butterflies are insects that have large, often brightly colored wings, and a conspicuous, fluttering flight.
The group comprises the superfamilies Hedyloidea and Papilionoidea.
Butterfly fossils date to the Paleocene, about 56 million years ago.
Some facts about butterflies include.
Butterfly wings are transparent.
There are almost 20,000 butterfly species.
Butterflies use their feet to taste.
Butterflies only live for a few weeks.
Butterflies have a liquid diet.
Butterflies actually have four wings, not two.
When you see butterflies flying in groups the groups of butterflies are called kaleidoscope.
However although most commonly called kaleidoscope the group of butterflies are also sometimes called and known as a swarm of butterflies.
Either name of a swarm of butterflies or kaleidoscope of butterflies is the correct way to refer to them.
I just call a group of butterflies a swarm of butterflies because it's easier to say the word swarm and remember the word swarm than it is to say the word kaleidoscope or remember the word kaleidoscope.
So you can call the group of butterflies either a swarm of butterflies or a kaleidoscope of butterflies and either of them will be correct.
Because they are a swarm of butterflies when they are flying in a group.
