Bats tease the art lover (8)
I believe the answer is:
aesthete
'art lover' is the definition.
(I've seen this before)
'bats tease the' is the wordplay.
'bats' indicates anagramming the letters (I've seen this in other clues).
'tease'+'the'='teasethe'
'teasethe' is an anagram of 'AESTHETE'.
(Other definitions for aesthete that I've seen before include "Someone sensitive to beauty in art" , "One is particularly appreciative of beauty" , "Person with deep interest in art and beauty" , "Person seeing beauty in art" , "Sensitive chap" .)
