Little Stanley confused by industrious insects (4)
I believe the answer is:
ants
This clue might be a double definition.
'little stanley confused' is the first definition.
I know that 'little' relates to this answer.
'industrious insects' is the second definition.
(I've seen this in another clue)
'by' is the link.
Can you help me to learn more?
(Other definitions for ants that I've seen before include "Busy little insects" , "Hard workers" , "Six-foot insects" , "They live in a formicary" , "workers found returning" .)
