From them I'd get insect (5)
I believe the answer is:
midge
'insect' is the definition.
(midge is a kind of insect)
'from them i'd get' is the wordplay.
'from' indicates the answer is hidden within the clue.
'MIDGE' is hidden within 'them id get'.
(Other definitions for midge that I've seen before include "Tiny biting fly" , "Tiny swarming insect" , "Minute mosquito-like fly" , "Small person" , "Small, gnat-like fly" .)
