Big dead ant ID. For the smallest ant, there's another observation: https://www.naturalista.mx/observations/36603829.
The Paratrechina longicornis raided the foraging area of the Leaf-cutter ants, killing them all. This ant was carrying her "prey" upwards on a 3 meter wall. It took her several hours to complete the task. There is a previous observation for the leaf-cutter ants when they were alive: https://www.naturalista.mx/observations/36603051
ID para la hormiga arriera vencida. La hormiga pequeña la arrastró verticalmente hasta su hormiguero. Le tomó varias horas subir una pared de 3 metros, sin recibir ayuda de sus congéneres. Ese día, las hormigas negras pequeñas atacaron la zona de forrajeo de las arrieras y mataron a muchas.
