Army ant colonies are worth close attention, as they are full of fascinating and poorly studied associates. Here, an ant-mimicking rove beetle runs in a nighttime raiding column in the Ecuadorian cloud forest. The mimicry is likely intended to fool the beetle's predators rather than the army ants, which have poor vision. Mindo, Pichincha, Ecuador.
