Nesomyrmex itinerans

Quick Summary

• Difficulty: Unknown, limited documented care information available
• Origin & Habitat: Venezuela, Neotropical region. Original specimens collected from Cattleya orchid flowers ^[1].
• Colony Type: Unconfirmed, no specific data on colony structure
• Size & Growth:
  • Queen: Size data unavailable, no measurements recorded in type specimens
  • Worker: Size data unavailable, no measurements recorded in type specimens
  • Colony: Unknown, no data available
  • Growth: Unknown
  • Development: Unknown, no development data available for this species (Direct development data unavailable for this species)
• Antkeeping:
  • Temperature: Keep at 24-28°C, condition-based recommendation for tropical Venezuelan species
  • Humidity: Maintain moderate to high humidity (60-80%), condition-based recommendation matching tropical forest origin
  • Diapause: No, tropical species from Venezuela does not require diapause
  • Nesting: Based on orchid collection, likely arboreal or associated with vegetation. Provide naturalistic setup with cork, twigs, or wooden sections. Test tubes work for founding but adding plant material simulates natural habitat.
• Behavior: Behavior is unstudied for this species. Nesomyrmex species are generally calm and non-aggressive. They likely forage in vegetation given their orchid association. Small size suggests moderate escape risk, use standard barriers.
• Common Issues: lack of documented care information makes successful keeping uncertain, tropical species may decline if kept too cool or dry, wild-caught colonies difficult to find since rarely collected, colony growth rate is unknown, arboreal nature may require specialized setups

Nest Preferences and Housing

Nesomyrmex itinerans was originally collected from orchid flowers, suggesting association with vegetation ^[1]. In captivity, a naturalistic setup with cork bark, twigs, or wooden sections works well. These ants likely prefer nesting in pre-existing cavities rather than excavating soil. Y-tong (AAC) nests with narrow chambers or plaster nests with plant material included are suitable. Test tubes work for founding colonies, but adding small organic material like twigs or cork pieces simulates their likely arboreal habitat.

Feeding and Diet

Diet is unstudied for this specific species. Nesomyrmex species are typically omnivorous like most Myrmicinae ants. They likely accept sugar sources (honey water, sugar water) and protein (small insects like fruit flies, pinhead crickets, mealworms). Their collection from orchids suggests they may forage in vegetation, possibly collecting honeydew from aphids or scale insects. Offer sugar water constantly, and protein prey 2-3 times per week. Remove uneaten prey after 24-48 hours to prevent mold. ^[1]

Temperature and Seasonal Care

As a tropical species from Venezuela, Nesomyrmex itinerans requires warm conditions. Keep the nest area at 24-28°C. Use a heating cable on one side of the nest to create a gentle gradient, but avoid overheating. Room temperature in most homes may be too cool. Unlike temperate species, they do not require winter diapause. Maintain stable temperatures year-round. Sudden temperature drops should be avoided.

Defense Mechanism

Nesomyrmex belongs to the Myrmicinae subfamily and Crematogastrini tribe. Members of this tribe typically have a modified, flattened spatulate stinger used to wipe or smear venom onto enemies rather than piercing flesh. This is a general taxonomic characteristic of the tribe.
