A Bug fighter is a small Yeerk spacecraft that is piloted by one Hork-Bajir and one Taxxon. They resemble cockroaches, hence the name, are about as big as a school bus, and have two long serrated spears on their sides that point forward which are actually its Penetrator-Class Dracon Beams. They can be modified to travel underwater.
