Chrysalis originally found in flatter meadow flower (9)
I believe the answer is:
buttercup
'meadow flower' is the definition.
(I've seen this before)
'chrysalis originally found in flatter' is the wordplay.
'originally' says to take the initial letters.
'found in' is an insertion indicator.
'flatter' becomes 'butterup' (buttering up is a kind of flattering).
The initial letter of 'chrysalis' is 'c'.
'c' inserted into 'butterup' is 'BUTTERCUP'.
(Other definitions for buttercup that I've seen before include "Dockside seller" , "Rich yellow wild flower" , "weedy type" , "Bright yellow flower" , "Meadow flower poisonous to cattle" .)
