Crematogaster reticulata

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Southeast Asia, southern Thailand, Malaysia (Peninsula and Borneo), and Brunei. Inhabits developed forests and nests in dead twigs or dead leaves on trees ^[1].
• Colony Type: Unconfirmed, colony structure has not been studied for this specific species.
• Size & Growth:
  • Queen: Size data unavailable, no total length measurements provided.
  • Worker: Size data unavailable, no total length measurements provided.
  • Colony: Colony size estimate unknown, research does not provide specific data.
  • Growth: Moderate, tropical species with year-round activity expected.
  • Development: Unknown, no specific data on development time. (Development time is unclear for this species.)
• Antkeeping:
  • Temperature: Keep warm, roughly 24-28°C, based on tropical habitat inference ^[1].
  • Humidity: Keep nest substrate consistently moist but not waterlogged, with a humidity gradient, as they nest in forests ^[1].
  • Diapause: No, this is a tropical species, so no diapause required.
  • Nesting: Arboreal nester, prefer tight, enclosed spaces. Use Y-tong or plaster nests ^[1][2].
• Behavior: Crematogaster ants are known for their acrobat behavior, raising their gaster when threatened ^[2]. They are generally docile but small, so escape prevention is critical due to their size.
• Common Issues: escape prevention is critical due to their very small size, they can squeeze through tiny gaps, tropical species may struggle in air-conditioned rooms or cold climates, arboreal nesting means they need humidity control, too dry causes colony decline, intermediate workers may be mistaken for queens by inexperienced keepers, wild-caught colonies may carry parasites that can devastate captive colonies

Nest Preferences and Housing

Crematogaster reticulata is an arboreal species that naturally nests in dead twigs and dead leaves suspended in trees within developed forests ^[1]. In captivity, you should replicate these conditions as closely as possible. A Y-tong (AAC) nest works well because it provides the dark, enclosed chambers these ants prefer. Alternatively, a plaster formicarium with small, tight chambers scaled to their tiny size is suitable. Avoid large, open spaces. Adding small twigs to the outworld gives them natural foraging surfaces. Keep the nest humid, these forest ants need moisture, but ensure ventilation to prevent mold.

Feeding and Diet

Crematogaster reticulata is omnivorous and will accept both sugar sources and protein. In the wild, they forage for honeydew and small insects. In captivity, provide sugar water or honey constantly. For protein, offer small prey like fruit flies or pinhead crickets 2-3 times per week. Remove uneaten prey after 24-48 hours to prevent mold. ^[2]

Temperature and Seasonal Care

As a tropical species, Crematogaster reticulata requires warm temperatures. Based on tropical habitat, keep the nest area at 24-28°C for optimal brood development ^[1]. A heating cable can create a gradient. Avoid temperatures below 20°C. They do not require diapause.

Behavior and Temperament

Crematogaster reticulata displays acrobat ant behavior, raising the gaster when threatened ^[2]. They are generally not aggressive toward keepers. Workers are active foragers. Their small size makes escape prevention critical. Intermediate workers are notable and may serve specialized roles ^[1].
