Crematogaster biroi

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.

Crematogaster biroi is an excellent choice for ant keepers who enjoy fast, active, and visually unique species. Their constant movement and interesting defensive behavior make them very entertaining to observe.

At Esthetic Ants we provide strong and healthy colonies with multiple queens and a starter group of workers, ensuring rapid development and a successful start. Because of their fast growth and high activity, this species is ideal for keepers who want to see quick results in colony expansion.

If you are looking for a lively and dynamic ant species, Crematogaster biroi is a great addition to your collection.

Temperature
Crematogaster biroi prefers warm tropical conditions between 24 and 30°C. Heating is recommended to maintain activity and colony growth.

Humidity
The nest should have moderate to high humidity around 60 to 80 percent, while the outworld can be slightly drier.

Food
Provide a varied diet consisting of:
sugar water or honey water as a primary energy source
small insects such as fruit flies, crickets, or mealworms for protein
occasionally fruit or ant jelly

Hibernation
This species does not require a winter diapause due to its tropical origin.

Nest and setup
Crematogaster biroi thrives in arboreal setups. Acrylic nests, cork nests, or natural setups with wood and vertical structures are highly recommended. Providing climbing space is important due to their natural behavior.

Escape prevention
This species is fast and very good at escaping. Strong escape prevention such as PTFE is essential.

Defense
Workers do not have a strong sting but can release defensive chemicals and may bite when disturbed. They are active and defensive but manageable with proper care.
