How to feed Veromessor pergandei
Veromessor pergandei is a desert harvester ant from the US Southwest that forages in columns. It lives mostly on seeds, with very little sugar. It likes a warm, dry nest.
What does Veromessor pergandei eat?
- Seeds (main food): small untreated seeds (millet, chia, dandelion), refreshed weekly.
- Protein: a few cut insects for the brood, once a week.
- Sugar: very little, optional.
- Tip: keep one corner of the nest dry and a warm foraging area.
How much to feed
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 (optional) | 0.1 g / week |
| 50 (Small) | 3 prey items every 4 days | 1 drop (optional) | 0.3 g / week |
| 150 (Growing) | 8 prey items every 7 days | 2 drops (optional) | 0.9 g / week |
| 400 (Established) | 19 prey items every 7 days | 4 drops (optional) | 2.4 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.
Hibernation
Light hibernation from December to February, at 10–15 °C.
Common mistakes
- Keeping the nest humid: it is a desert species.
- Too much sugar: the colony barely uses it.
- Hibernating too cold: a light rest is enough.
