Flier, tough to manage, some recalled (4)
I believe the answer is:
moth
'flier' is the definition.
(something which flies)
'tough to manage some recalled' is the wordplay.
'some' indicates a hidden word.
'recalled' says the letters should be written backwards.
'htom' can be found hidden inside 'tough to manage'.
'htom' in reverse letter order is 'MOTH'.
(Other definitions for moth that I've seen before include "Night flying insect" , "Small insect that lays its eggs in cloth or fabric" , "Night flier" , "Fairy like 13" , "Four-winged insect" .)
