Supplementary Video 1 (mov 185 k)
A fight between two fru ^C males. The fight begins with low-intensity aggression (fencing), and rapidly escalates to mid- and high-intensity components (lunging and boxing, respectively).

Supplementary Video 2 (mov 267 k)
A fight between two fru ^C females. One female drives the other off the food source, using low-intensity aggression (fencing) and mid-intensity components (head-butts and shoving).

Supplementary Video 3 (mov 269 k)
A fight between two fru ^F males. The two males jostle over the resource using female-style aggression involving head-butting and shoving. Fencing is also observed.

Supplementary Video 4 (mov 751 k)
A fight between a fru ^F male and a fru ^C female. Both flies fight using female-style aggression, as exemplified by the shoves and head-butts that accompany fencing. The fru ^F male does not court the fru ^C female.

Supplementary Video 5 (mov 659 k)
Fights between a fru ^F male and a fru ^M female. The fru ^M female chases the male away, mostly using lunges in (a), as well as fencing in both videos. Towards the end of the scene shown in (b), the female rises to box—an aggressive gesture to which a male fly would normally respond but the fru ^F male does not. In both videos, the male mostly fences and retreats. Neither fly courts.

Supplementary Video 6 (mov 133 k)
Fights between a fru ^F male and a fru ^M female. The fru ^M female chases the male away, and both flies engage in fencing. Neither fly courts. Towards the end of the scene, the female rises to box—an aggressive gesture to which a male fly would normally respond but the fru ^F male does not.
