Present adherent misguided occasionally (4,3,5)
I believe the answer is:
here and there
'occasionally' is the definition.
(thesaurus)
'present adherent misguided' is the wordplay.
'present' becomes 'here' (both can mean in attendance).
'misguided' is an anagram indicator (letters guided into the wrong places).
'adherent' with letters rearranged gives 'andthere'.
'here'+'andthere'='HERE AND THERE'
(Other definitions for here and there that I've seen before include "In various places" , "Sporadic localities?" , "in several places" .)
