A pair of Dolichoderus quadrimaculatus foragers gather the remains of a rainforest katydid killed the preceding night by a rodent, as well as rodent feces left at the site. Ants provide a full-service waste removal system for many ecosystems.

Pheidole obscurithorax stays ahead of the competition using group retrieval of food (in this case, a scavenged cockroach carcass).  Working together, the ants can usually get the bounty home before a more aggressive species usurps their find.
