Remove coat in boring task to catch insect (6)
I believe the answer is:
hornet
'insect' is the definition.
(hornet is a kind of insect)
'remove coat in boring task to catch' is the wordplay.
'remove coat in' indicates the central letters (the external letters can be called a 'coat').
'boring task' becomes 'chore' (I've seen this before).
'to catch' becomes 'net' (netting is a kind of catching).
The middle of 'chore' is 'hor'.
'hor'+'net'='HORNET'
(Other definitions for hornet that I've seen before include "Troublesome nester" , "Vespa" , "Large wasp with vicious sting" , "A large wasp with serious sting" , "Small flier" .)
