Striped insect (4)
I believe the answer is:
wasp
'striped insect' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for wasp that I've seen before include "Flyer" , "Insect with a sting in its tail" , "White Anglo-Saxon Protestant" , "Insect with a formidable sting" , "Insect often irritating in summer" .)
