Kaleidoscope
collective noun /kəˈlaɪdəskəʊp/ — What you call a group of butterflies — a moving stained-glass window.
Definition
The collective noun for a group of butterflies in flight — named for the shifting, colour-filled patterns they create as they move together.
Beyond the definition
A kaleidoscope of butterflies is one of the rare collective nouns that almost exceeds its subject. Watch a hundred butterflies rise from a meadow at once — the colours shifting, overlapping, never repeating — and you understand immediately why someone chose this word. It is not a group. It is a moving stained-glass window.
Origin & history
From Greek kalos 'beautiful' + eidos 'form' + skopein 'to look at'. Invented by Scottish physicist David Brewster in 1817 to describe his optical device. Later adopted as the collective noun for butterflies — fitting for something that makes patterns from beauty.

A kaleidoscope of butterflies
Many butterflies gathering together on damp ground.
Here, “kaleidoscope” names the whole gathering. Notice the animals together rather than looking for one individual with that name. The photograph illustrates the group; it is not evidence that this particular scene inspired the expression.
