Dig me out an insect (5)
I believe the answer is:
midge
'an insect' is the definition.
(midge is a kind of insect)
'dig me out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'dig'+'me'='digme'
'digme' with letters rearranged gives 'MIDGE'.
(Other definitions for midge that I've seen before include "Gnat" , "Tiny swarming insect" , "Small, gnat-like fly" , "Small flying insect" , "Be an obstacle" .)
