What is difference between butterfly and snail?

Butterflies and snails are both members of the animal kingdom, but they belong to different phyla. Butterflies are insects belonging to the phylum Arthropoda, while snails are mollusks belonging to the phylum Mollusca. One key difference is their mode of locomotion - butterflies have wings and can fly, while snails move by gliding on a muscular foot or by crawling. Additionally, butterflies undergo complete metamorphosis, with distinct larval, pupal, and adult stages, while snails develop through a process called torsion during their embryonic stage.
