Crematogaster minutissimaSpecies Introduction
Claustral. One or more queens sealed off in a tube rearing their first generation.
Native to the Southeast's hardwood forests. In the wild these ants can be found nesting in leaf litter on the forest floor, or sticks higher up off the ground. These ants can have colonies capable of having dozens of queens! Colonies sometimes produce intermediate workers (intercastes) which are noticeably larger than the normal workers.
Highly polygynous, while having relatively small colonies. Generalists that will take many types of insects for protein, and loves carbohydrates. Great climbers so make sure to apply a fluon barrier in the outworld.
Formicarium
Small twig-style or thin-channel formicaria work well, our Arboreal Ant Nest is ideal. A secure nest and a fluon barrier for the outworld is recommended for these tiny escape-artists.
Water & Humidity
More tolerant to high humidity than other Crematogaster, allow proper humidity gradient throughout the nest. Avoid overwatering.
Recommended to use TrapJaw Labs PVA sponges for founding due to improved humidity.
Keep a liquid feeder with water (distilled, purified, or spring) in the foraging area at all times.
Carbohydrates
These ants want carbohydrates but it's a relatively minor component of their diet.
Occasional small honey drop in the outworld is fine.
We recommend providing sugar-water (we use our Ant Nectar Mix) and fresh-water liquid feeders in the outworld at all times.
Protein
Protein-loving. We suggest feeding protein 2–3 times a week.
Generalists, accepts a wide range of pre-killed insects. TrapJaw Labs feeds our C. minutissima colonies with pre-killed D. melanogaster, D. hydei fruit flies, and pre-cut mealworms.
Two to three times per week. Increase amounts to scale with brood development.
Maintenance
Week 1: Dark, warm, gently humid, and undisturbed. No food yet.
Weeks 3–5: First workers appear. Start protein 2–3×/week, and put out a 24/7 sugar feeder.
Months 2+: Steadily growing colony. Intermediate workers may appear. Colonies produce alates earlier than most ants.
Diapause is not required for this species.
Care Summary
- Protein 2–3×/week
- Sugar via liquid feeder
- Moderate humidity
- Gradient 76–88°F
- Expect early alate production
