Game insect (7)
I believe the answer is:
cricket
I believe this clue is a double definition.
'game' is the first definition.
(I know that cricket is a type of bat-and-ball game)
'insect' is the second definition.
(I know that cricket is a type of orthopteran)
(Other definitions for cricket that I've seen before include "Game - "basically baseball on Valium" (Robin Williams)" , "Insect - sport" , "short leg seen on this field?" , "Jumping insect" , "a jumper" .)
