An isopod falls prey to a raid of Labidus spininodis army ants. Mindo, Pichincha, Ecuador.
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.
Neivamyrmex army ants are specialist predators of the brood of other ant species. Here, N. californicus raid the brood nest of the pavement ant Tetramorium immigrans. California, USA
