Devil's garden

[2] Devil's gardens can reach sizes of up to 600 trees and are inhabited by a single ant colony, containing up to 3 million workers and 15,000 queens.

[5][6] Inhabited by the ant Myrmelachista schumanni, devil's gardens, in different regions of the Amazon, can be dominated by different tree species.

[1] In southeastern Peru, devil's gardens are dominated by Cordia nodosa (Boraginaceae) and occasionally mixed with Tococa occidentalis (Melastomataceae).

[citation needed] In southeastern Ecuador and northeastern Peru the most common tree species found in devil's gardens are Duroia hirsuta (Rubiaceae).

[1] The ants make nesting sites in the hollow stems and leaves of the tree, called domatia.
