Dolichoderus flatidorsus

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Native to southern China, specifically Guangxi Province. Based on typical Dolichoderus habitat preferences in this region, they likely inhabit forested areas with access to rotting wood, tree bark, or arboreal nesting sites in humid tropical or subtropical environments ^[1].
• Colony Type: Colony structure is unconfirmed for this species. Dolichoderus species vary in their colony organization, with some being monogyne and others polygyne ^[1].
• Size & Growth:
  • Queen: Size data unavailable, inferred from Dolichoderus genus patterns to be approximately 6-8mm.
  • Worker: Size data unavailable, inferred from Dolichoderus genus patterns to be approximately 3-4mm.
  • Colony: Maximum colony size is unconfirmed for this species.
  • Growth: Growth rate is unconfirmed.
  • Development: Development time is unconfirmed for this species. (Specific development studies are not available for this species.)
• Antkeeping:
  • Temperature: Keep at 22-26°C. Southern Chinese species prefer warm, stable conditions. A slight temperature gradient allows ants to regulate their own exposure.
  • Humidity: Maintain moderate to high humidity. These ants prefer damp conditions similar to forest floor environments in southern China. Keep nest substrate moist but not waterlogged.
  • Diapause: Diapause requirements are unconfirmed for this species. Based on the temperate latitude of their native range in southern China, a mild winter rest period may be beneficial.
  • Nesting: In captivity, they do well in Y-tong (AAC) nests, plaster nests, or naturalistic setups with access to both moist chambers and dry areas. They often prefer darker nesting areas.
• Behavior: Generally calm and non-aggressive temperament. Like other Dolichoderus species, they are not known for stinging but may emit a defensive odor when threatened. Workers are active foragers, primarily collecting honeydew from aphids and small insects. They have moderate escape risk due to their small size, ensure enclosures have tight-fitting lids and consider barrier methods like fluon on smooth surfaces.
• Common Issues: colonies may develop slowly due to limited species-specific information, escape prevention requires attention due to small worker size, use fine mesh and tight barriers, humidity control is important, too dry may cause issues, too wet promotes mold, limited species-specific information means keepers must adapt care from genus-level knowledge

Nest Preferences and Housing

Dolichoderus flatidorsus originates from the Guangxi region of southern China, where the climate is warm and humid year-round. In the wild, these ants likely nest in rotting wood, under loose bark, or in tree hollows, typical arboreal or semi-arboreal nesting sites for the genus. In captivity, they adapt well to various nest types including Y-tong (AAC) nests, plaster nests, or naturalistic setups with soil and wood elements. They prefer darker nesting chambers and will often relocate if their nest is too exposed. Provide a humidity gradient within the nest so workers can choose optimal conditions. A test tube setup works well for founding colonies, with migration to a larger formicarium once the colony reaches 30-50 workers. ^[1]

Feeding and Diet

Like other Dolichoderus species, Dolichoderus flatidorsus is omnivorous with a preference for sugary substances and protein. In captivity, offer sugar water or honey as a constant energy source. For protein, provide small insects such as fruit flies, small crickets, or mealworm pieces. They also readily accept honeydew, which can be simulated with sugar water offerings. Feed protein 2-3 times per week, adjusting based on colony size and consumption. Remove uneaten prey after 24-48 hours to prevent mold growth. Fresh water should always be available.

Temperature and Seasonal Care

As a species from southern China, Dolichoderus flatidorsus prefers warm conditions between 22-26°C. Maintain stable temperatures, as fluctuations can stress the colony. During summer months, room temperature is often suitable. In winter, based on the temperate latitude of their native range, they may benefit from a diapause period at cooler temperatures. Reduce feeding during this rest period and avoid disturbing the colony. Resume normal care in spring when temperatures rise.

Behavior and Colony Dynamics

Dolichoderus flatidorsus exhibits typical Dolichoderus colony behavior, relatively peaceful, with workers that are active foragers rather than aggressive defenders. When threatened, they may release a distinctive odor as a defensive mechanism, a characteristic shared across the Dolichoderinae subfamily. Workers forage individually, collecting honeydew from aphids and hunting small prey. The colony will expand gradually, with queen laying eggs once established. First workers (nanitics) are typically smaller than mature workers.
