State feeling upset about trap, doodlebug overhead (8)
I believe the answer is:
virginia
'state' is the definition.
(I know that Virginia is a state)
'feeling upset about trap doodlebug overhead' is the wordplay.
I cannot really see how this works, but
'about' could be 'a' (abbreviation in Chambers) and 'a' is found in the answer.
'trap' could be 'gin' (gin trap is a kind of animal trap) and 'gin' is present in the answer.
'doodlebug' could be 'vi' (the V-1 was a World War II flying bomb) and 'vi' is present in the answer.
This explanation may well be incorrect...
(Other definitions for virginia that I've seen before include "US state, home of the Blue Ridge Mountains" , "state (in Havana)" , "Where to find Richmond" , "US East coast state" , "Variety of creeper, bright red in Autumn" .)
