Fructivorous insect's food (7)
I believe the answer is:
aliment
'fructivorous insect's food' is the definition.
'aliment' can be an answer for 'food' (aliment is a kind of food). I am not certain of the 'fructivorous insect's' bit.
'insect's food' is the wordplay.
I cannot really understand how this works, but
'food' could be 'lime' (lime is a kind of food) and 'lime' is found within the answer.
'insect' could be 'ant' (ant is a kind of insect) and 'ant' is present in the leftover letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for aliment that I've seen before include "Old word for food" , "Nourishment" , "Something which nourishes - meal tin (anag)" , "Sustenance" .)
