Nest bee nests, a resource also targeted by the tropical hornet. Symbiosis, ranging from feeding on waste to obligate parasitism, is common within the nest. Ant nests alone support symbiotes spanning six classes of arthropods which includes 35 families just from the beetles. Nest A nest is a structure built by certain animals to hold eggs, offspring, and, occasionally, the animal itself. Although nests are most closely associated with birds, members of all classes of vertebrates and some invertebrates construct nests. They may be composed of organic material such as twigs, grass, and leaves, or may be a simple depression in
Red harvester ant high availability of food and good foraging conditions, therefore a favorable cost-benefit ratio for the foragers exists. If the patroller return rate is too high, it may be a warning of danger, such as the sighting of a predatory lizard. A lower return rate could indicate lack of available food, or heavy competition Ant foraging is guided by chemical signals that lead the ants up to 50–60 m from the nest at times. Once an ant has decided to forage, it will almost always continue until it has found food to take back to the nest; 90% of returning foragers
