Dacatria templaris

Dacatria templaris

Dacatria templaris is a rare and cryptic ground-dwelling ant species and the only member of its genus. Workers are small at about 3.5mm, with a distinctive brick-red coloration and a dull, dirt-covered appearance that makes them remarkably well-camouflaged in their forest floor habitat ^[1]. This species is closely related to Proatta and is known from only a handful of collections across South Korea, China, and Vietnam, making it one of the more elusive ants in the hobby ^[2]. The workers have unusual morphological features including modified clypeus structures and distinctive humeral tubercles on the promesonotum that help distinguish them from similar ants ^[1].

Quick Summary

• Difficulty: Expert
• Origin & Habitat: This species inhabits well-developed forests in temperate to subtropical regions of East Asia, including South Korea, China, and Vietnam. It nests in leaf litter and underground, typically in humid forest floor environments at elevations around 500-1000 meters ^[1][3].
• Colony Type: Colony structure is unconfirmed. Only a single queen has been collected (not fully described), and colony size in the wild is unknown. Based on related Proatta species, expect small to moderate colony sizes.
• Size & Growth:
  • Queen: Not fully described, a queen has been collected but not formally described in scientific literature ^[3]
  • Worker: About 3.5mm total length (HL 0.86mm, HW 0.68mm) ^[3]
  • Colony: Unknown, only a few collections have been made and colony size has not been documented ^[2]
  • Growth: Unknown, no development data exists for this species
  • Development: Unknown, no direct observations of development. Related Proatta species suggest 6-10 weeks at optimal temperature, but this is an estimate. (Development timeline has not been documented. Expect moderate growth based on related species in the Crematogastrini tribe.)
• Antkeeping:
  • Temperature: Keep at room temperature around 20-24°C. This species comes from temperate to subtropical regions of East Asia, so moderate warmth is appropriate. A slight gradient allowing cooler areas around 18-20°C is recommended.
  • Humidity: High humidity is essential, these ants live in forest floor litter and underground nests. Keep the nest substrate consistently moist but not waterlogged. Mist occasionally and provide a water source.
  • Diapause: Likely required. Given its distribution in Korea and China where winters are cold, expect a winter rest period of 2-3 months at temperatures around 10-15°C. Reduce feeding and keep them in a cool location during this period.
  • Nesting: Ground-dwelling species that nests in litter and underground. In captivity, a naturalistic setup with moist substrate (soil/peat mix) works well, or a Y-tong/plaster nest with chambers kept humid. They prefer tight, enclosed spaces similar to their natural underground nests.
• Behavior: Workers are highly cryptic and tend to freeze when disturbed, making them difficult to detect, this is a survival adaptation. They are ground-dwelling and likely forage slowly through leaf litter. Escape risk is moderate, at 3.5mm they are small but not tiny. Standard escape prevention with fine mesh is sufficient. Temperament is likely docile, similar to related Proatta species.
• Common Issues: extreme rarity makes obtaining a colony very difficult, they are rarely found in the hobby, no documented captive breeding success means care protocols are experimental, cryptic freezing behavior means workers may seem inactive or dead when they are simply hiding, ground-dwelling nature requires specific humidity control that can lead to mold issues if not managed, lack of published care information means keepers must adapt from related species

Discovery and Rarity

Dacatria templaris represents a fascinating case of a species that was only described in 1994 from a single worker collected in South Korea ^[3]. Since then, only a handful of collections have been made across its range in Korea, China, and Vietnam, making it one of the rarest ants in the Myrmicinae subfamily. The genus Dacatria contains only this single species, and its closest relative is Proatta ^[4]. This rarity means that captive colonies are essentially nonexistent in the antkeeping hobby, and anyone acquiring these ants would be pioneering their captive care.

Natural Habitat and Nesting

In the wild, Dacatria templaris inhabits well-developed forests with dense leaf litter. The species nests in the litter layer and underground, preferring humid microhabitats ^[1]. Collections have been made at elevations between 500-1000 meters in nearly subtropical environments with bamboo groves on southern mountain slopes, as well as in evergreen forests ^[3]. This ground-dwelling lifestyle means they are adapted to stable, humid conditions with limited temperature fluctuation. Their workers have a distinctive brick-red coloration and tend to become covered in dirt, providing excellent camouflage in the forest floor environment.

Identification and Morphology

Workers of Dacatria templaris are distinctive and can be recognized by several unique features. They have a subrectangular head with a shallow central longitudinal furrow, and the lateral portion of the clypeus is modified into a distinct ridge or wall in front of the antennal insertion ^[1]. The promesonotum has a pair of rounded, low humeral tubercles, and the propodeal spines are long. The workers are monomorphic (all the same size) and measure approximately 3.5mm in total length. Their cryptic appearance and freezing behavior when disturbed make them extremely difficult to detect in the field, when their nests are exposed, the workers simply freeze motionless, blending in with the surrounding soil and litter.

Caring for Dacatria templaris in Captivity

Since this species has never been documented in captivity, all care recommendations are experimental and based on inference from related species and natural habitat. Provide a naturalistic setup with a deep layer of moist substrate (a mix of soil and peat works well) to allow for their natural underground nesting behavior. Maintain high humidity by keeping the substrate consistently moist but not waterlogged, and mist the setup occasionally. Room temperature around 20-24°C is appropriate for this temperate to subtropical species. Given their small size and ground-dwelling nature, escape prevention should include fine mesh barriers. Feed a typical ant diet of sugar water or honey and protein sources like small insects, but be aware that acceptance of various foods is completely unconfirmed for this species.

Seasonal Care and Winter Rest

Based on the natural distribution of Dacatria templaris in Korea and China, where winters are cold, this species almost certainly requires a winter rest period. During autumn, gradually reduce temperatures over 2-3 weeks to around 10-15°C and maintain this for 2-3 months through winter. Reduce feeding significantly during this period, the colony will be less active and consume less. In spring, slowly warm them back to room temperature and resume normal feeding. This diapause period is essential for the health of colonies from temperate regions and helps trigger proper reproductive cycles in spring.
