(Scene 1, 0:00:00-0:00:11) An ant was carrying a termite. A dipterous insect eyed it and seized the termite. The ant and dipterous insect pulled the termite from both side. The ant moved into a narrow space under a dead leaf and the dipterous insect released its hold on the termite.
(Scene 2, 0:00:11-0:00:24) An ant was carrying a termite. A dipterous insect grabbed the termite, and the two pulled the termite from both side. The dipterous insect kept pulling although the ant moved under a dead leaf. The dipterous insect, however, ran away when another ant appeared and bit it.
(Scene 3, 0:00:24-0:010:02) A dipterous insect was sitting and waiting for an ant with a termite came out from under a dead leaf. As the ant came out, the dipterous insect seized the termite and the two pulled the termite from both sides. Although the ant was tugging both termite and dipterous insect toward itself, the dipterous insect succeeded in robbing the prey. However, it was chased by another ant and released its hold on the termite. The ant started to carry the termite again and the dipterous insect retreated.
(Judgment) A winner is the ant as it kept the termite. But it is not clear what the dipterous insect was actually doing while it had a grip on the termite. The final judgment should wait further observations.
