Blender yielding a meal during tea-time (9)
I believe the answer is:
chameleon
'blender' is the definition.
(animal which blends into its environment)
'yielding a meal during tea-time' is the wordplay.
'yielding' is a deletion indicator.
'during' means one lot of letters goes inside another.
'tea' becomes 'cha' (cha is a type of tea).
'time' becomes 'eon' (eon is a kind of time).
'meal' with 'a' taken away is 'mel'.
'cha'+'eon'='chaeon'
'mel' placed inside 'chaeon' is 'CHAMELEON'.
(Other definitions for chameleon that I've seen before include "Self-camouflaging lizard" , "Lizard that can adapt its colours to background" , "Animal that changes colour" , "Creature adding colour" , "blender" .)
