Normal insect dropping head on flower (7)
I believe the answer is:
natural
'normal' is the definition.
('natural' can be similar in meaning to 'normal')
'insect dropping head on flower' is the wordplay.
'insect' becomes 'gnat' (gnat is a kind of insect).
'dropping head' means to remove the first letter.
'on flower' becomes 'ural' (I've seen this before. I am not sure about the 'on' bit.**).
'gnat' with its initial letter taken away is 'nat'.
'nat'+'ural'='NATURAL'
Can you help me to learn more?
(Other definitions for natural that I've seen before include "Not synthetic or man-made" , "in a pack, not wild?" , "Not man-made; off-white" , "Unsophisticated" , "Innate - neither flat nor sharp" .)
