Army ants are blind and rely on pheromones to track the ones in front. If one ant intersects with its old trail then it results in a circular death trap where they spiral until they die from exhaustion.
However, the contrarian army ants might survive. https://t.co/ruQhtGUei9
军蚁是盲人，依靠信息素来追踪前方的蚂蚁。如果一只蚂蚁与它的老路相交，就会形成一个圆形的死亡陷阱，在那里它们盘旋着，直到精疲力竭而死。
然而，逆势军蚁可能会存活下来。https://t.co/ruQhtGUei9
