Butterflies & Moths

[Richard Grace]

I read a book when I was a child about how moths and butterflies can
flit.  From memory they have tiny "feathers" on their wings which act as
"flaps" and by controlling them they can dramatically change their drag
on the top or either side which allows them to flit.

Are my recollections correct - or even close?

If not -  how do they flit.
