Dolichoderus sundari

Quick Summary

• Difficulty: Unknown
• Origin & Habitat: Northeastern India (Meghalaya, Arunachal Pradesh). Found in forest reserves at elevations in the Khasi Hills. Type specimens collected from inside a wild fruit of a creeper, suggesting arboreal or semi-arboreal nesting habits in humid forest environments ^[1][2].
• Colony Type: Unknown colony structure, no data on whether they are single-queen or multi-queen colonies.
• Size & Growth:
  • Queen: Size data unavailable, queen has not been described in scientific literature
  • Worker: 3.24-4.00mm ^[1]
  • Colony: Unknown
  • Growth: Unknown
  • Development: Unknown, no development data exists for this species (No direct development data exists for this species.)
• Antkeeping:
  • Temperature: Keep at room temperature (20-26°C). No specific requirements documented.
  • Humidity: Maintain moderate to high humidity. Keep nest substrate consistently moist but not waterlogged.
  • Diapause: Unknown, likely no true diapause given tropical/subtropical distribution in northeastern India.
  • Nesting: Based on type specimen collection from inside a wild fruit, they likely prefer arboreal or semi-arboreal nesting sites. In captivity, a small Y-tong (AAC) nest or plaster nest with tight chambers scaled to their tiny size would likely work well. Avoid large, open spaces.
• Behavior: Behavior is poorly documented. Dolichoderus ants generally have defensive glands that can produce foul-smelling secretions when threatened. Their tiny size means escape prevention is critical, they can squeeze through very small gaps. They are likely arboreal or semi-arboreal foragers.
• Common Issues: escape prevention is critical due to their very small size, use fine mesh barriers, no captive breeding data exists, this species may be extremely difficult to establish from wild-caught queens, humidity requirements are unconfirmed and may require experimentation, growth rate is unknown, beginners may lose patience, virtually no information on acceptable foods, feeding may require experimentation, this species is extremely rare in the antkeeping hobby with no established husbandry protocols

Appearance and Identification

Dolichoderus sundari workers are tiny ants measuring 3.24-4.00mm in total length. They have a distinctive two-tone coloration: the head, thorax, pedicel node, and abdomen are pitch black, while the mandibles, antennae, and legs are brownish yellow. The body is covered with numerous hairs, giving them a somewhat fuzzy appearance. The head is massive with cordate (heart-shaped) mandibles, and the eyes are large and placed toward the front of the head. The pedicel node is scale-like and inclined forward, and the abdomen is convex and massive. These ants are very similar to their close relative Dolichoderus sulcaticeps but can be distinguished by their smaller size and differences in thoracic sculpture ^[1].

Distribution and Habitat

This species is endemic to India, meaning it is found nowhere else in the world. It has been recorded in the northeastern states of Meghalaya (particularly the East Khasi Hills in Nongkhyllem Reserve Forest) and Arunachal Pradesh ^[2]. The type specimens were collected from inside a wild fruit of a creeper in Nongkhyllem Reserve Forest, which suggests this species may be arboreal or semi-arboreal in its nesting habits, living in forest canopies rather than on the ground ^[1]. The humid, forested habitat of their range indicates they likely require moist conditions.

Nesting in Captivity

Based on the type specimen collection from inside a wild fruit, Dolichoderus sundari likely prefers arboreal or semi-arboreal nesting sites. In captivity, a small Y-tong (AAC) nest or plaster nest with chambers scaled to their tiny 3-4mm size would be appropriate. Avoid large, open spaces that would be unnatural for such small ants. Given their likely origin in humid forest environments, the nest should maintain consistent moisture without becoming waterlogged. A small water reservoir connected to the nest chamber can help maintain humidity. Tight-fitting lids and fine mesh are essential for escape prevention due to their very small size.

Feeding and Diet

The diet of Dolichoderus sundari has not been documented in scientific literature. Based on typical Dolichoderus genus behavior, they likely feed on honeydew from aphids and scale insects, as well as small insects and other arthropods. In captivity, you should likely offer sugar water or honey water as a constant energy source, along with small live prey such as fruit flies, pinhead crickets, or other appropriately-sized insects. Given their tiny size, prey items must be very small. Start with sugar sources and observe acceptance, then gradually introduce small protein sources.

Temperature and Seasonal Care

Dolichoderus sundari is found in northeastern India, which has a subtropical to temperate climate depending on elevation. Keep them at room temperature (roughly 20-26°C). They likely tolerate a range from roughly 20-28°C but should be kept stable. Unlike temperate species, they likely do not require a true diapause (winter hibernation), though they may show reduced activity during cooler months. If your room temperature falls within this range, no additional heating may be needed. For cooler environments, a small heating cable on one side of the nest can create a gentle gradient. Always ensure there is a cooler area within the nest so ants can self-regulate.

Challenges and Considerations

Dolichoderus sundari is an extremely poorly documented species in captivity. There is no established husbandry knowledge base for this ant, meaning you will essentially be pioneering its care. Key challenges include: escape prevention (their tiny 3-4mm size means they can squeeze through gaps that seem sealed), unconfirmed humidity requirements (start with moderate-high humidity and adjust based on colony health), unknown diet acceptance (be prepared to experiment with different foods), and unknown growth rate (patience will be essential). This species is not recommended for beginners due to the lack of documented care information. If you obtain a queen, be prepared for a potentially difficult founding period with no guarantees of success.
