Crematogaster rogenhoferi

• Queen: 8–9 mm
• Workers: 3–4.5 mm

• Insects: fruit flies, mealworms, small roaches, waxworms, crickets (prefer soft-bodied or pre-killed)
  • Sugar sources: sugar syrup (4:1 water to honey or sugar), diluted honey
  • Soft fruits: banana, apple, melon (in moderation)
  • Protein jelly (formicarium-safe)
  • Occasional protein boost: unseasoned cooked egg or fish flakes

💡 Crematogaster rogenhoferi is an aggressive forager and highly protein-driven, especially during larval stages. Colonies consume large amounts of food relative to their size and respond quickly to protein presence.

• Humidity: Arena: 40–60% | Nest: 60–80%
  • Temperature: Arena: 22–30 °C | Nest: 25–28 °C
  • Diapause: Not required — tropical/subtropical species; maintain stable warmth year-round

Crematogaster rogenhoferi is a striking arboreal ant native to Southeast Asia, known for its heart-shaped gaster and fast, aggressive movement. Its colonies are highly dynamic, with active trails and intense food competition, especially when protein is offered.

In nature, they nest in hollow twigs, tree bark, or crevices, forming sprawling colonies that may extend over multiple chambers. In captivity, they thrive in setups that mimic vertical or arboreal environments. Acrylic or naturalistic nests with moisture gradients and climbing space are ideal. They are escape-prone — tight lids and fluon barriers are essential.

These ants show strong territoriality and will readily engage in defensive behaviors. Their gaster-raising stance and use of formic acid spray are signature traits. Despite their size, they are bold, quick, and highly visible, making them popular among advanced hobbyists.

Queens are prolific egg-layers, and with warmth and food, colonies expand rapidly. Brood development is fast, allowing quick colony scaling under proper conditions.

Crematogaster rogenhoferi is a fast-paced, visually stunning tropical ant species, ideal for experienced keepers looking for a high-activity, protein-hungry colony. With their signature gaster posture and arboreal habits, they offer constant motion and fascinating behavior. Best suited for secure, warm, high-humidity setups with plenty of vertical space and frequent feeding schedules.
