Crossword Genius

Somehow eating insects could be demanding (13)

Ross

I believe the answer is:

necessitating

'demanding' is the definition.
('necessitate' can be a synonym of 'demand')

'somehow eating insects' is the wordplay.
'somehow' is an anagram indicator.
'eating'+'insects'='eatinginsects'
'eatinginsects' anagrammed gives 'NECESSITATING'.

'could be' acts as a link.

(Another definition for necessitating that I've seen is " Causing a need".)

I've seen this clue in The Independent.
