D. gigas is a large species of ant, native to Southeast Asian forests.

The ant is an effective forager, utilizing both efficient communication and recruitment.

A handful of these ants may meet at night to engage in what has been observed to be ritual battle.

[citation needed] Colonies consist of typically about 7,000 workers, distributed unevenly among several nests.

[citation needed] This species is found in Southeast Asian rain forests from Sumatra, Singapore, Malaysia, Borneo to Thailand.
