Crematogaster russata

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Known only from Bolivia in the Neotropical region. The specific habitat type is not documented in available literature ^[2].
• Colony Type: Unconfirmed, colony structure has not been documented for this species.
• Size & Growth:
  • Queen: Size data unavailable, typical Crematogaster queens are larger than workers, but no species-specific measurements exist
  • Worker: Size data unavailable, no documented measurements for this species
  • Colony: Unknown, no colony size data available
  • Growth: Unknown
  • Development: Unknown, development has not been directly studied for this species (Based on typical tropical Crematogaster patterns, development likely takes several weeks to first workers at warm temperatures.)
• Antkeeping:
  • Temperature: Keep at warm tropical temperatures, aim for 24-28°C based on the species' Bolivian origin and typical Crematogaster preferences.
  • Humidity: Moderate to high humidity is typical for neotropical species. Keep nest substrate lightly moist but not waterlogged. Provide a water source in the outworld.
  • Diapause: Unlikely, as a tropical species from Bolivia, they probably do not require a hibernation period.
  • Nesting: In nature, Crematogaster typically nest in dead wood, under bark, or in hollow stems. In captivity, a Y-tong (AAC) nest, plaster nest, or naturalistic setup with wood or decaying bark works well.
• Behavior: Crematogaster russata will display typical acrobat ant behavior, raising their gaster when threatened. They are generally not aggressive toward keepers but will defend the nest. Workers are small and active, foraging for honeydew, small insects, and nectar. Escape prevention should be thorough given their small size, they can squeeze through tiny gaps.
• Common Issues: lack of documented care information makes species-specific guidance difficult, small size means escape prevention must be excellent, use fine mesh barriers, tropical humidity requirements may cause mold issues if ventilation is poor, no specific diet acceptance data, start with standard ant foods and observe, wild-caught colonies may have unknown parasites or diseases

Identification and Taxonomy

Crematogaster russata was originally described by W.M. Wheeler in 1925 as a subspecies of Crematogaster crinosa, based on worker specimens collected from San Fermin, Bolivia. The species remained classified as a subspecies until John T. Longino's 2003 revision of Costa Rican Crematogaster, where it was raised to full species status ^[1]. It belongs to the Crematogaster crinosa species complex, a group of closely related species that require further taxonomic study to clarify their boundaries. The genus Crematogaster is part of the subfamily Myrmicinae and is known for the distinctive behavior of workers raising their abdomen over their head like an acrobat when threatened.

Natural History and Distribution

This species is known only from Bolivia, making it one of the less widely distributed Crematogaster species. The exact habitat type is not documented in available literature. As a neotropical species from Bolivia, it likely inhabits warm, humid environments typical of that region. The specific elevation range and microhabitat preferences remain unknown. ^[2]

Crematogaster Genus-Level Care Guidance

Since species-specific care information for C. russata is extremely limited, care recommendations must be based on general Crematogaster husbandry knowledge. Crematogaster ants are arboreal or semi-arboreal in the wild, often nesting in dead wood, hollow stems, or under bark. In captivity, they adapt well to Y-tong (AAC) nests, plaster nests, or naturalistic setups with wood material. They prefer warm, humid conditions matching their tropical origins. Diet typically consists of sugar sources and protein. Workers are small and excellent climbers, so escape prevention must be thorough with fine mesh barriers.

Housing and Nesting

For housing Crematogaster russata, use a nest that provides enclosed, humid chambers. A Y-tong (AAC) nest with narrow chambers works well, as does a plaster nest or a naturalistic setup with rotting wood pieces. The nest material should retain some moisture without becoming waterlogged. Provide a water test tube in the outworld as a hydration source. Because of their small size, ensure all connections between the nest and outworld are secure, these tiny ants can squeeze through remarkably small gaps.

Feeding and Nutrition

While specific dietary preferences for C. russata are unconfirmed, Crematogaster species generally accept sugar water, honey, or maple syrup as carbohydrate sources. They also consume small insects for protein, including fruit flies, pinhead crickets, mealworms, and other appropriately-sized prey. In the wild, they likely tend aphids or collect honeydew from other homopterans. Feed sugar sources continuously and offer protein prey 1-2 times per week, adjusting based on colony size and consumption. Remove uneaten prey after 24 hours to prevent mold.
