Tempting creature mischievously present (7)
I believe the answer is:
serpent
'tempting creature' is the definition.
(as in the serpent in Eden)
'mischievously present' is the wordplay.
'mischievously' is an anagram indicator (I've seen this in other clues).
'present' is an anagram of 'SERPENT'.
(Other definitions for serpent that I've seen before include "exhibit at zoo" , "(In literature) a snake" , "Malicious person" , "Snake - old wind instrument" , "Venomous snake" .)
