The common term for a group of butterflies is a "kaleidoscope." This poetic term reflects the vibrant and colorful nature of butterflies, which are known for their beautiful wings and diverse patterns. Butterflies are part of the order Lepidoptera, and they undergo a remarkable metamorphosis from caterpillar to adult. Groups of butterflies can often be seen gathering in specific areas, such as during migration or in areas with abundant flowers. The collective term "kaleidoscope" captures the aesthetic appeal of these insects as they flutter about in nature.
