Discothyrea icta

Quick Summary

• Difficulty: Unknown
• Origin & Habitat: Trinidad, a Caribbean island nation off the coast of Venezuela. The only specimens were collected at the Imperial College of Tropical Agriculture at St Augustine. ^[1]
• Colony Type: Unknown, only queen specimens have been collected, workers have never been documented. The colony structure is completely unstudied. ^[1]
• Size & Growth:
  • Queen: Size data unavailable, the original description did not include measurements, and no subsequent specimens have been found. The species is noted as overall smaller compared to related species Discothyrea bobi. ^[1]
  • Worker: Unknown, workers have never been described ^[1]
  • Colony: Unknown, no colony has ever been documented ^[1]
  • Growth: Unknown
  • Development: Unknown, no development data exists for this species (This species has never been kept in captivity, so no development timeline is available)
• Antkeeping:
  • Temperature: Unconfirmed. Based on Trinidad's tropical climate, they likely prefer warm conditions. Start in the mid-to-low 20s Celsius and observe colony activity.
  • Humidity: Unconfirmed. Trinidad is a humid tropical island, so they likely need moderate to high humidity. Keep substrate consistently moist but not waterlogged.
  • Diapause: Unknown, no data on seasonal behavior. As a tropical species from an island near the equator, they likely do not require a diapause period.
  • Nesting: Unconfirmed. Most Discothyrea species nest in soil, rotting wood, or under stones in shaded forest areas. A naturalistic setup with moist substrate would be a reasonable starting point.
• Behavior: Completely unobserved. No behavioral data exists for this species in scientific literature. Other Discothyrea species are typically cryptic, slow-moving, and predatory on small arthropods. Escape risk cannot be assessed since worker size is unknown. ^[1]
• Common Issues: This species has never been kept in captivity, there is no established care protocol, Workers have never been documented, so housing requirements are completely unknown, No feeding observations exist, diet is inferred only from genus patterns, The species may not exist in the wild anymore or may be extremely localized, No one has documented nuptial flight timing or mating behavior

Why This Species Is Exceptional

Discothyrea icta represents one of the most poorly documented ant species in the world. Since its description in 1939,only two queen specimens have ever been collected, both from the same location in Trinidad. No workers, no colonies, no behavioral observations, no ecological data. This isn't just a species that's rarely kept in captivity, it's a species that has essentially never been observed alive by scientists. Every aspect of its biology, from what it eats to how it nests to when it mates, remains completely unknown. This makes it impossible to provide reliable care guidance, and it would be irresponsible to pretend otherwise. ^[1][2]

What We Know From the Genus

While D. icta itself is a complete mystery, we can make some educated guesses based on other Discothyrea species. The genus contains tiny ants that are predatory on small arthropods like springtails and mites. They have a characteristic curved stinger and are typically found in moist forest habitats. Most species appear to be claustral founders, with queens sealing themselves in a chamber to raise their first workers alone. However, these are genus-level patterns, not confirmed facts for D. icta specifically. Any care advice based on this would be speculative at best. ^[3]

The Challenge of Rarity

This species may be extinct or on the brink of extinction. Only two specimens have been found in nearly 85 years, both from the same location that has likely seen significant development since the 1930s. The Imperial College of Tropical Agriculture at St Augustine is now part of the University of the West Indies campus, and Trinidad has experienced substantial urbanization. If any wild colonies exist, they would be extremely localized. This also means there's no established population for antkeepers to work with, unlike common species like Lasius niger or Camponotus floridanus, you cannot find D. icta queens during nuptial flights. ^[1]

Is Keeping This Species Possible?

At present, keeping Discothyrea icta is not practically possible for hobbyists. No one has documented a living colony, so no queens are available from the wild. The species has never been imported or bred in captivity. Even if a queen were somehow obtained, we have no information about what to feed her, what temperature she needs, or how long her development takes. For antkeepers interested in rare and unusual species, it would be far more practical to seek out other Discothyrea species that are better documented, such as Discothyrea testacea (known from North America) or various Discothyrea species from the Neotropics that have been more recently collected and described. ^[3]
