Cataglyphis golestanica

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Endemic to the Hezar Pich Hills in Gorgan city, Golestan Province, Iran. This species nests in bare, unvegetated lands that formed as a result of destructive human activities, sometimes in harvested wheat fields with scant vegetation. Nests have a simple entrance hole at ground level with no mound, are exposed to full sunlight, and are found at low altitudes between 192-315 meters above sea level ^[1].
• Colony Type: Colony structure is unconfirmed. The species shows monomorphic to monophasic worker size variation, meaning workers come in one size or slight size range. No queen biology has been documented yet for this newly described species ^[1].
• Size & Growth:
  • Queen: Undescribed, queen measurements not yet documented in scientific literature
  • Worker: Size data unavailable, the research provides head length measurements but not total body length. Related Cataglyphis species typically range from 4-8mm total length.
  • Colony: Unknown, this is a newly described species with limited field data
  • Growth: Unknown, no development studies exist yet
  • Development: Unconfirmed, development timeline has not been studied for this species (Development timeline has not been directly studied.)
• Antkeeping:
  • Temperature: Keep warm, around 24-28°C. These are desert-adapted ants that thrive in sunny, hot conditions in the wild. A heating cable on one side of the nest creates a suitable gradient.
  • Humidity: Low to moderate, prefer dry conditions. In nature they nest in bare, sun-exposed areas with minimal vegetation. Allow the nest to dry out between waterings.
  • Diapause: Likely yes, based on the temperate climate of northern Iran where winters are cold. Expect a winter rest period of 2-3 months around 10-15°C.
  • Nesting: Y-tong (AAC) nests work well for this size. The species prefers dry, warm conditions with full exposure to heat. Avoid moist substrates, these are not forest-floor ants.
• Behavior: Fast-moving and active foragers, typical of the Cataglyphis genus. They are daytime hunters that venture out in the heat to hunt for prey. Workers are slender with long legs, built for speed. As a Formicinae ant, they lack a functional sting but can spray formic acid as defense. Escape prevention should be moderate, they are not among the smallest ants but can move quickly.
• Common Issues: new species means limited care information, expect some trial and error, cold temperatures will slow or stop activity and may harm brood, overly humid conditions can be harmful, these are desert-adapted ants, wild-caught colonies may be difficult to locate as the species has a very restricted range, hibernation failure is possible if proper cooling period is not provided

Nest Preferences and Housing

Cataglyphis golestanica naturally nests in bare, unvegetated ground with simple entrance holes at soil level, exposed to full sunlight. In captivity, Y-tong (AAC) nests work well for this species. The key requirement is providing warmth and dry conditions, these ants are not suited to humid, enclosed setups. A test tube setup can work for founding colonies, but transition to a proper nest once the colony reaches 20+ workers. Avoid moist substrates and ensure the nesting area can warm up under a heating cable or mat. The species prefers narrow chambers scaled to their body size but not so tight that workers cannot move freely. ^[1]

Feeding and Diet

Cataglyphis ants are typically generalist predators and scavengers. In the wild, they forage for small insects and other arthropods in hot conditions where other predators are less active. In captivity, offer small live prey such as fruit flies, small crickets, and mealworms. Sugar sources like honey water or sugar water are typically accepted, though protein should form the primary diet. Feed every 2-3 days, removing uneaten prey after 24 hours. A constant sugar water supply is recommended. Given this is a newly described species with no specific dietary studies, be prepared to experiment with prey acceptance.

Temperature and Seasonal Care

These desert-adapted ants require warm conditions to thrive. Maintain nest temperatures around 24-28°C, with a slight gradient allowing workers to choose their preferred warmth. A heating cable placed on top of the nest (never underneath where it can dry out moisture too quickly) works well. Based on the species' origin in northern Iran, expect a diapause requirement. During winter (roughly November through February in the Northern Hemisphere), reduce temperatures to around 10-15°C to allow the colony its natural rest period. Do not feed during hibernation and minimize disturbance. Cold temperatures outside this range can be fatal or cause prolonged inactivity. ^[1]

Behavior and Colony Dynamics

Cataglyphis golestanica is a fast-moving, diurnal forager typical of the genus. Workers have elongated legs built for speed, allowing them to hunt prey and scavenge during the hottest parts of the day when competitors are less active. The species shows monophasic size variation, workers come in a range of sizes from minor to major, but all fall within a single size continuum rather than distinct castes. Major workers are notably larger with more pronounced coloration (reddish head and mesosoma), while minors are smaller and more brownish. Workers likely communicate through chemical signals and may use tandem running to recruit nestmates to food sources, though this specific behavior has not been documented for the species. As members of the Formicinae subfamily, these ants lack a functional sting and instead spray formic acid as their primary defense mechanism. ^[1]

Acquiring This Species

Cataglyphis golestanica was only described in 2025,making it one of the newest ant species in the hobby. Wild colonies are extremely difficult to obtain because the species has an extremely restricted range, it is only known from the Hezar Pich Hills near Gorgan city in Golestan Province, Iran. This is not a species you will find readily available from suppliers. If available at all, expect to pay a premium for captive-reared colonies. Never collect from the wild in Iran without understanding local laws regarding insect collection. The best approach is to wait for captive propagation to establish in the antkeeping hobby, which may take several years. ^[1]
