Leptogenys Kitteli

They are inactive at night, but during the day these army ants (leptogenys kitteli, 基氏细猛蚁) scour every part of Yuelu Mountain (嶽麓山). Individual ants wander about like itinerant warriors. When seen in groups they are almost always dragging worms, grasshoppers or other spoils back into their own abodes, which are often makeshift and temporary nests, precariously put together under debris and old leaves. There is something inappropriate and anthropomorphic about referring to an ant as 'aggressive', but the term is often applied to them because they move quickly and are efficient at finding food.
