"Mighty" is an adjective used to describe things or people that are powerful or strong (this does not have to be in the physical sense). It is often used on account of size, so it is a bit funny to think of a small butterfly as being "mighty." However, the speaker has chosen this word to show that despite its small size, the butterfly is sturdier and more powerful than it appears. In fact, "small but mighty" is an expression often used to describe things that are small but powerful. Ex: This motorcycle is small but powerful. Ex: The mighty corporation employs millions around the world.
