Hen possibly spotted insect (8)
I believe the answer is:
ladybird
This clue is a double definition.
'hen possibly' is the first definition.
(female or 'lady' bird)
'spotted insect' is the second definition.
(insect with spots)
(Other definitions for ladybird that I've seen before include "Red spotted beetle" , "old children's book" , "spotted one that flies" , "spotted crawler" , "Black-spotted red beetle" .)
