Season very good for trapping black antelope (9)
I believe the answer is:
springbok
'antelope' is the definition.
(springbok is a kind of antelope)
'season very good for trapping black' is the wordplay.
'season' becomes 'spring' (spring is a season).
'very good for' becomes 'ok' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'trapping' indicates putting letters inside.
'black' becomes 'b' (abbreviation as in pencil hardness).
'spring'+'ok'='springok'
'springok' going around 'b' is 'SPRINGBOK'.
Can you help me to learn more?
(Other definitions for springbok that I've seen before include "antelopes" , "Sportsman" , "South African symbol" , "Antelope" , "jumper" .)
