Insect runs away with deer (9)

I believe the answer is:

antelopes

I'm a little stuck... Click here to teach me more about this clue!

'away with deer' is the definition.
I can't judge whether this defines the answer.

'insect runs' is the wordplay.
'insect' becomes 'ant' (ant is a kind of insect).
'runs' becomes 'elopes' (I am not sure about this - if you are sure you should believe this answer much more).
'ant'+'elopes'='ANTELOPES'

Can you help me to learn more?

(Other definitions for antelopes that I've seen before include "Wild animals" , "Gazelles, impalas etc" , "Springboks, say" .)

I've seen this clue in the Sydney Morning Herald.
