Woman, with time in prison, spotted beetle (8)
I believe the answer is:
ladybird
'spotted beetle' is the definition.
(I've seen this before)
'woman with time in prison' is the wordplay.
'woman' becomes 'lady' (lady is a kind of woman).
'with' says to put letters next to each other.
'time in prison' becomes 'bird' (bird is slang for time spent in prison).
'lady'+'bird'='LADYBIRD'
(Other definitions for ladybird that I've seen before include "Small round spotted beetle" , "Kind of beetle" , "that's spotted in gardens" , "spotted crawler" , "Common insect" .)
