It comes to light, naturally (4)
I believe the answer is:
moth
'it comes to light' is the definition.
(I've seen this in another clue)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for moth that I've seen before include "Usually nocturnal insect" , "Insect of the order lepidoptera" , "One of 5 [FAIRIES]" , "Insect; MND fairy" , "Night flying insect" .)
