Insect queen maybe raised feeler (7)
I believe the answer is:
antenna
'feeler' is the definition.
(I know that feeler can be written as antenna)
'insect queen maybe raised' is the wordplay.
'insect' becomes 'ant' (ant is a kind of insect).
'queen maybe' becomes 'Anne' (Queen Anne, 18th-century queen).
'raised' says the letters should be written in reverse (going up in a down clue).
'anne' written backwards gives 'enna'.
'ant'+'enna'='ANTENNA'
(Other definitions for antenna that I've seen before include "receiver" , "Insect's sensory appendage" , "sensitive feeler" , "Feeling part" , "Feature of dish" .)
