Flying beast got hermit agitated (5,4)
I believe the answer is:
tiger moth
'flying beast' is the definition.
(type of moth)
'got hermit agitated' is the wordplay.
'agitated' indicates an anagram.
'got'+'hermit'='gothermit'
'gothermit' anagrammed gives 'TIGER-MOTH'.
(Other definitions for tiger moth that I've seen before include "Woolly bear" , "producer of woolly bears" , "Plane" , "Spotted flyer" , "Insect - aeroplane" .)
