fleck

I'm a little stuck... Click here to teach me more about this clue!

'bit' is the definition.
(I know that bit can be written as fleck)

I don't understand the remainder of the clue.

(Other definitions for fleck that I've seen before include "Speckle" , "Streak or spot" , "Small patch of colour/light" , "Small patch of colour" , "Little spot" .)

I've seen this clue in the Sydney Morning Herald.
