Maybe fly where Mormon can be found? (6)
I believe the answer is:
insect
'maybe fly' is the definition.
(I know that fly is a type of dipteran)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for insect that I've seen before include "Nicest (anag) - six-footer" , "Possibly fly" , "Bee or beetle, for example" , "Contemptible person" , "Small air-breathing arthropod" .)
