Technomyrmex champasakensis

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Highland coffee plantation at ~1000m elevation in Champasak Province, southern Laos – endemic to this region ^[1][2]
• Colony Type: Single queen (monogyne). The observed wild colony had one queen and over 10,000 workers ^[1].
• Size & Growth:
  • Queen: 3.80 mm ^[1]
  • Worker: 2.97–3.47 mm ^[1]
  • Colony: Over 10,000 workers in wild colonies ^[1]
  • Growth: Moderate
  • Development: Estimated 6–8 weeks at 25–28°C (This is an estimate because no development studies exist for this newly described species.)
• Antkeeping:
  • Temperature: Aim for 24–28°C. They come from a tropical highland area in Laos ^[1]. Avoid letting it drop below 20°C for long periods.
  • Humidity: Keep the nest moderately moist but not waterlogged. Their coffee plantation home is humid, so a slight misting of the outworld or a water source helps.
  • Diapause: Unlikely – as a tropical species, they do not need hibernation. A small temperature drop to ~22°C in winter is okay but not required.
  • Nesting: They naturally nest between and under leaves ^[1]. In captivity, Y-tong (AAC), plaster, or soil nests work well. Provide dark, enclosed chambers with some moisture. Test tubes work for founding.
• Behavior: These ants are generally docile and not aggressive to keepers. As Dolichoderinae ants, they lack a stinger but can exude a sticky, foul-smelling chemical from their anal gland as a defense. Workers are active foragers. Because they are small (under 3.5 mm), tight seals and fine mesh are needed to prevent escapes. They will tend to scale insects or aphids if present, which makes them interesting to watch.
• Common Issues: sensitive to temperatures below 20°C – can cause colony decline or death if prolonged, newly described species means some details about captive care are unknown and may require experimentation, large colony size potential (10,000+ workers) means you must plan for a spacious formicarium as the colony matures, small workers can squeeze through tiny gaps – thoroughly seal all connections and openings

Housing and Nest Preferences

In the wild, Technomyrmex champasakensis builds its nest between and under coffee tree leaves ^[1]. This tells us they like dark, enclosed spaces with some humidity. For captive care, a Y-tong (AAC) nest or plaster nest works well – both can keep moderate moisture without getting waterlogged. Because workers are small (under 3.5 mm), make sure the nest chambers and tubes are appropriately sized. A test tube setup is fine for a founding colony, but you will need to upgrade to a larger formicarium once the colony reaches 50–100 workers. Since they are naturally arboreal, you could add artificial leaves or a naturalistic setup with live plants, but this is optional. The key point is to provide a dark, humid nesting space.

Feeding and Diet

In the wild, this species tends scale insects and feeds on their honeydew ^[1]. So, give them a constant source of sugar – like honey water, sugar water, or commercial ant sugar water. For protein, offer small insects such as fruit flies, pinhead crickets, or pieces of mealworm. Feed protein 2–3 times per week and remove any leftovers after 24–48 hours to avoid mold. They will likely accept artificial honeydew or sugar solution readily. Since they naturally tend hemipterans, having a few aphids or scale insects in the outworld can be a fun way to mimic their natural feeding behavior, but it isn't necessary for their health.

Temperature and Seasonal Care

Technomyrmex champasakensis comes from a tropical highland area in Laos ^[1]. They do best at 24–28°C. Extended periods below 20°C can stress or kill them. A heating mat or cable on one side of the nest helps create a warm spot and lets them thermoregulate. Because it is tropical, they do not need a true diapause. If you want to give them a slight winter rest, you can drop the temperature to around 22°C, but it's not required. Keep them warm year-round for steady colony growth.

Colony Structure and Growth

The only wild colony found had one queen and over 10,000 workers ^[1]. This tells us they can build large, single-queen colonies. Growth is expected to be moderate – they develop at a steady pace, not extremely fast like some invasive tropical species. Based on typical Dolichoderinae development, first workers will likely appear within 6–8 weeks under good warm temperatures. As the colony grows, you will need to expand the formicarium. A colony of several thousand workers needs a spacious nest and a decent-sized outworld to forage.

Behavior and Temperament

Technomyrmex ants are generally calm and won't attack you. As Dolichoderinae ants, they have no stinger. Instead, they exude a sticky, foul-smelling chemical from an anal gland when threatened – this is their defense, not formic acid. Workers are active and will forage around the enclosure. Their small size (under 3.5 mm) lets them slip through tiny gaps, so use fine mesh and check all connections. They are not especially aggressive toward other insects but will defend their nest. In captivity, they will form foraging trails and, if you provide them, they will tend to scale insects or aphids. This makes them enjoyable to observe. ^[1]
