Scold one that eats insects (5)
I believe the answer is:
shrew
I believe this clue is a double definition.
'scold' is the first definition.
(both can mean a nagging woman)
'one that eats insects' is the second definition.
(type of rodent)
(Other definitions for shrew that I've seen before include "Petruchio tamed one" , "Long-nosed mammal" , "Virago" , "Woman to be tamed?" , "Small mammal with a long snout" .)
