Social means you like to be around people.

Ah, Butterfly is an insect social butterfly.

So a social butterfly must be an insect that likes to fly around people.

So I went to a party last weekend and guess who was there?

Jane from Accounting.

Let me guess.

She sat in the corner of the whole time and didn't talk to anyone like she doesn't work.

No, just the opposite.

She was quite the social butterfly, moving from one person to the next, laughing and talking All night long.

A social butterfly moves among people at a gathering easily like a butterfly flying from flower to flower.

A social butterfly enjoys interacting with people, and that's English in a minute.
