Temnothorax pardoi

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Native to the western Mediterranean: Spain, Portugal, France, Gibraltar, and Morocco ^[6]. Lives in oak forests (Quercus pyrenaica and Q. faginea) and heathland from near sea level up to about 1,400 m elevation ^[3][7]. Usually nests in decomposing twigs and branches on the ground, in humid spots shaded from direct sun ^[1].
• Colony Type: Likely monogyne (single queen) based on nest observations ^[1].
• Size & Growth:
  • Queen: Estimated 4-5 mm, based on typical Temnothorax size
  • Worker: 2-3 mm ^[1][2]
  • Colony: Unknown, likely small, under 200 workers, typical of the genus
  • Growth: Moderate
  • Development: Estimated 6-10 weeks at room temperature, based on related species (No direct development data for this species, estimate from typical Temnothorax patterns)
• Antkeeping:
  • Temperature: Room temperature (20-24 °C) works well. They tolerate a wide range, found in both warm and cold months in the wild ^[8], but keep stable.
  • Humidity: Keep the nest moderately damp, like their natural decomposing wood. Provide moisture without waterlogging ^[1].
  • Diapause: Unknown, based on temperate range, likely needs a cool winter period (2-3 months at 10-15 °C). No direct documentation.
  • Nesting: Y-tong (AAC) or plaster nests with small, tight chambers. Add a piece of soft wood or cork inside to mimic their natural twig-nesting habit ^[1]. Avoid dry, exposed conditions.
• Behavior: Peaceful and shy. They forage alone, not in groups. Like other Crematogastrini, they have a flattened stinger used to smear venom rather than sting, it's mild. Their tiny size means they can slip through very small gaps, so use fine mesh on openings.
• Common Issues: tiny size makes escapes likely without fine mesh barriers, use 0.5 mm or smaller mesh, colonies stay small, don't expect large worker numbers, wild-caught colonies may be stressed from relocation and have low survival, decomposing wood in nests can mold if too wet, balance humidity carefully, slow growth tests patience, avoid overheating or overfeeding founding colonies

Housing and Nest Setup

Because Temnothorax pardoi is so small, the nest needs tight chambers. Y-tong (AAC) or plaster nests work well. In the wild, they nest in decomposing branches of plants like dwarf gorse (Ulex minor) in humid heathland, often shaded by heather ^[1]. You can mimic this by adding a small piece of soft wood or cork inside the nest chamber. For the outworld, use a container with a tight lid and fine mesh (0.5 mm or smaller) on any openings, these ants can crawl through tiny gaps. Provide a small water tube and a shallow feeding dish.

Feeding and Diet

Like most Temnothorax, T. pardoi hunts small arthropods. Offer live prey such as springtails, fruit fly larvae, or tiny crickets. They also visit the diaspores of plants like Helleborus foetidus, so they may accept soft fruits or seeds occasionally ^[4][5]. Give small prey 2-3 times a week for established colonies, and offer a drop of sugar water or diluted honey weekly. Don't give large prey, they can't handle it.

Temperature and Seasonal Care

Room temperature (20-24 °C) is fine. They're found across a wide elevation range (248-1,406 m) ^[7] and are equally active in cold and warm months ^[8], so they're fairly adaptable. In winter, expect less activity. Based on their temperate distribution, provide a cool period (10-15 °C) for 2-3 months. Don't feed during deepest hibernation, but keep a little moisture available.

Behavior and Colony Dynamics

This is a shy, cryptic species. Workers forage individually, not in groups. Colonies stay small, likely under 200 workers. They are non‑aggressive to keepers and use a spatulate stinger to smear venom instead of piercing (a typical defense of Crematogastrini). In the wild they are considered native‑rare ^[9] and are important seed dispersers for plants like Helleborus foetidus ^[4][5]. They are not subterranean (non‑hypogaeic) ^[8] and prefer to stay in leaf litter and decomposing wood.

Finding and Acquiring

In the wild, look for nests in decomposing twigs and branches, especially in heathland with dwarf gorse (Ulex minor) or in oak forests where they hide under bark or moss ^[1][3]. They prefer dead wood that is already soft and rotting, often sheltered by heather or gorse ^[1]. The species is patchy and rare, so finding a colony takes patience. If you collect, do so responsibly, check local laws (not known to be protected) and only take a part of the colony to avoid harming the local population.
