Crematogaster biroi is a small to medium sized arboreal ant species native to Southeast Asia. Like other Crematogaster species, they are known for their distinctive heart-shaped gaster which they can raise over their body when alarmed. Colonies are typically polygynous, meaning they can contain multiple queens, and can grow quickly under the right conditions. Due to their fast development, active behavior, and unique appearance, Crematogaster biroi is a very interesting species for ant keepers.

In the wild Crematogaster biroi inhabits tropical forests where they live primarily in trees, branches, and hollow plant structures. They build nests in wood cavities, under bark, or inside hollow twigs. Colonies can spread across multiple nesting sites connected by foraging trails.
Workers are highly active and agile, constantly exploring their surroundings in search of food. They are opportunistic feeders and collect sugary liquids such as nectar and honeydew as well as small insects for protein. When disturbed, workers raise their gaster and can release defensive chemicals, which is typical behavior for this genus.
Colonies grow quickly and can become quite large, with continuous activity both inside the nest and in the foraging area.
