Aphaenogaster senilis is a long-legged black ant from southern Europe. It is omnivorous, collecting dead insects and a few seeds. Its founding is semi-claustral: the queen must be fed.

Guidelines for a colony with a moderate amount of brood, at 22–28 °C (72–82 °F):
| WORKERS | PROTEIN | SUGAR / 3–4 DAYS | SEEDS |
|---|---|---|---|
| 10 (Nanitics) | 1 prey item every 5 days | 1 drop | 0.1 g / week |
| 50 (Small) | 5 prey items every 4 days | 2 drops | 0.1 g / week |
| 150 (Growing) | 14 prey items every 3 days | 5 drops | 0.3 g / week |
| 400 (Established) | 34 prey items every 3 days | 13 drops | 0.7 g / week |
1 prey item = one insect the size of a fruit fly (2–3 mm). A medium cricket (1 cm) is worth about 50 prey items. 1 drop ≈ 0.05 mL. Seeds: 1 g ≈ 170 millet seeds ≈ 750 chia seeds; 1 teaspoon ≈ 4 g.
These are starting points. If food is left after 24 h, give less; if everything disappears fast and the brood grows, give more. The calculator also adjusts for brood and temperature.
Light hibernation from December to February, around 10–12 °C.
Yes: one small prey and one drop of sugar a week during founding.
A little, as a supplement to insects.
Protein every 3–5 days, sugar and seeds always available.
Amounts and timings are average guidelines, not rules. Always adjust to what you see in your own colony (leftovers, appetite, brood).
