Fungus-growing ant from the tropical Americas (introduced in Florida): it farms a fungus on what you give it (dry plant debris, oat flakes, insect fragments, caterpillar droppings). No regular prey or sugar, no hibernation, 24–28 °C and good humidity.

| WORKERS | PROTEIN | SUGAR |
|---|---|---|
| 10 | 1 small piece · Every 5 days | little or none |
| 50 | 3 small pieces · Every 4 days | little or none |
| 150 | 8 small pieces · Every 3 days | little or none |
| 400 | 19 small pieces · Every 3 days | little or none |
1 fruit fly ≈ a 2–3 mm insect; a medium cricket (1 cm) is about 50 fruit flies. 1 drop ≈ 0.05 mL.
Adjust to what you see: if food is left after 24 h, give less; if it all goes fast and the brood grows, give more.
Semi-claustral founding: the queen forages for fungus substrate. Offer tiny dry plant bits or oat flakes, no sugar.
No hibernation: keep it warm all year.
