Moths fluttering at noon, keeping to the far edge of wood (9)

'moths' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'fluttering at noon keeping to the far edge of wood' is the wordplay.
'fluttering' indicates an anagram.
'keeping' is an insertion indicator (some letters kept inside).
'the far edge of' suggests the final letters (the letter on the far end of the word).
The final letter of 'wood' is 'd'.
'at'+'noon'='atnoon'
'atnoon' with letters rearranged gives 'noonta'.
'to'+'d'='tod'
'noonta' enclosing 'tod' is 'NOTODONTA'.
