Temnothorax platycephalus

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Iberian Peninsula, Spain – Sierra de Cazorla (Jaén) and nearby Cuenca province. Found at high altitudes (1650–1796 m) in rocky mountain habitats ^[1][2].
• Colony Type: Monogyne – single queen colonies. Nests occur in rock crevices at high altitudes ^[1].
• Size & Growth:
  • Queen: Size data unavailable, inferred from genus as ~4–6 mm
  • Worker: Size data unavailable, inferred from genus as ~2.5–3.5 mm
  • Colony: Estimated up to 300 workers based on typical Temnothorax colony sizes
  • Growth: Moderate – based on genus patterns
  • Development: Estimated 6–10 weeks at optimal temperature, based on related species in the genus (Development time inferred from typical Temnothorax patterns – direct data for this species is unavailable.)
• Antkeeping:
  • Temperature: Keep at moderate room temperature, around 18–22 °C. These ants come from cool high-altitude Mediterranean mountains, so avoid sustained temperatures above 25 °C. A temperature gradient is helpful.
  • Humidity: Moderate to low. They inhabit well‑drained rocky areas, so let the nest dry out partially between waterings. Avoid constant high moisture.
  • Diapause: Yes – based on their high‑altitude origin, they likely require a winter dormancy period. Reduce temperature gradually and provide a cool resting period (approx. 2–3 months) if kept in a heated room year‑round.
  • Nesting: Rock crevice specialist. In captivity use Y‑tong (AAC) nests with narrow chambers, or naturalistic setups with flat stones on a sandy substrate. Provide tight, confined spaces, avoid large open nest chambers.
• Behavior: Peaceful and shy – they prefer to flee from threats rather than fight. This species belongs to the tribe Crematogastrini, which uses a smearing venom defense (modified stinger that wipes venom onto enemies rather than piercing), they are harmless to humans. Escape prevention is critical: workers are tiny (around 2–3 mm) and can squeeze through very small gaps.
• Common Issues: escape prevention is critical – workers are tiny (around 2–3 mm) and can fit through standard barriers., monogynous colony structure – you cannot keep multiple unrelated queens together., slow colony growth may frustrate beginners who expect rapid development., high‑altitude origin means they need cool temperatures – avoid overheating above 25 °C., rock crevice nesting requirement means they need tight, confined spaces – avoid large open nest chambers., very limited wild distribution makes this species rarely available in the hobby.

Housing and Nest Preferences

Temnothorax platycephalus is a rock crevice specialist – nests in the wild are monogynous and located in rock crevices at high altitudes (1650–1796 m) ^[1][4]. In captivity, replicate these tight, confined spaces. Y‑tong (AAC) nests with very narrow chambers work well, as do naturalistic setups with flat stones placed on a sandy substrate. The chambers should be scaled to the ants’ tiny size (workers ~2–3 mm total length) – passages must be small enough that workers feel secure. Avoid large open spaces inside the nest. A test tube setup can be used for founding, but be aware that the extreme small size of these ants makes escape through the cotton more likely than with larger species. Excellent escape prevention (fine mesh, tight seals) is essential from the start.

Temperature and Seasonal Care

These ants come from high elevations in the Sierra de Cazorla (1650–1796 m), where temperatures are cool to moderate ^[1][2]. Keep the nest area at 18–22 °C and avoid prolonged temperatures above 25 °C. They are adapted to seasonal temperature swings and likely require a winter dormancy period. To simulate their natural cycle, gradually reduce temperatures to 5–10 °C for 2–3 months (e.g., in a cool garage or cellar) and reduce feeding. If you keep them in a heated room year‑round, at least provide a cool zone within the setup. Avoid constant high heat, which can stress the colony.

Feeding and Diet

No detailed dietary studies are available for this species. Based on typical behavior of related Temnothorax, they likely accept small insect prey (fruit flies, pinhead crickets, springtails) and carbohydrate sources such as sugar water, honey water, or honeydew. Because workers are tiny (~2–3 mm), offer appropriately sized prey items. Provide sugar water or diluted honey regularly. Offer protein 2–3 times per week in small quantities. Their natural mountain habitat may have a limited prey spectrum, so avoid overfeeding with exotic items.

Colony Founding and Development

The founding method is not documented for this species. Based on patterns in the genus Temnothorax, queens are typically claustral – they seal themselves in a small chamber and raise the first workers without foraging – but this is not confirmed. If your queen is claustral, provide a dark, quiet test tube with water and clean cotton. Avoid disturbing her during the founding stage. Development time from egg to worker is estimated at 6–10 weeks at moderate temperatures (based on related species). Colony growth is moderate, expect several months to a year before you see a double‑digit workforce. Patience is essential during founding – excessive disturbance or inadequate conditions can easily cause failure.

Behavior and Temperament

Temnothorax platycephalus is a peaceful, shy ant. Workers avoid confrontation and retreat when threatened. They belong to the tribe Crematogastrini, whose members possess a modified flattened stinger used to smear venom onto enemies rather than pierce them – this defense is not dangerous to humans. They forage individually for small prey and honeydew. Their tiny size (workers ~2–3 mm) makes them easy to overlook in the outworld, and they are skilled escape artists. Ensure all barriers are escape‑proof. They show no aggression toward nestmates or the keeper and are ideal for observation if kept securely. ^[1]

Acquisition and Availability

This species has a very limited natural distribution – only confirmed from the Sierra de Cazorla (Jaén) and Cuenca province in Spain ^[1][2][4]. It is endemic to this small area, rarely collected, and almost never available in the general ant‑keeping hobby. If you do obtain a colony, it will likely come from a specialized breeder focusing on rare European species. This scarcity, combined with the specific care requirements, makes it a species for experienced keepers and collectors, not beginners.
