Forelius pruinosusSpecies Introduction
Claustral. A single newly-mated queen founds the colony alone. Their nuptial flights happen on hot mornings after rain.
Native to the Southeast's open, sandy habitats. In the wild they nest in open sand that is quite wet beneath their surface. Diurnal, peak activity at 90°F+.
Expect lots of foraging and trailing. They burn through energy fast, making them hungry for both protein and sugar. Keep the nest humid, the food stocked, and they will be a joy to watch.
Formicarium
Substrate nests (sand-based) replicate their optimal conditions best. A secure nest and a fluon barrier for the outworld is recommended for these small ants.
Water & Humidity
Very humid. Nests in moist, sandy soils in the wild. They can handle low humidity in the foraging area but the nest environment must be humid at all times.
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
Carbohydrate-loving. In the wild the workers spend their days trailing around the hot, coastal plains and burn through a lot of energy.
Honeydew honey or basic sugar water both work; honeydew honey better matches their wild micronutrient profile.
We recommend providing sugar-water (we use our Ant Nectar Mix) and fresh-water liquid feeders in the outworld at all times.
Protein
We suggest feeding F. pruinosus colonies fruit flies 2–3 times a week. The more frequent, the better.
TrapJaw Labs feeds our F. pruinosus colonies with pre-killed D. melanogaster and D. hydei fruit flies.
Twice per week. Increase amounts to scale with brood development.
Maintenance
Week 1: Settle the founding queen somewhere dark and undisturbed. Stress from disturbance can cause her to consume her own brood, so avoid checking on her during this process. If founding in a test tube with a TJL sponge, humidity and water will be maintained throughout this process.
Weeks 2–4: First workers appear. Start feeding protein (2–3×/week) and put out a 24/7 sugar feeder. You'll quickly see them take advantage of the food they're given and the colony will increase in size.
Months 2+: Maintain humidity and liquid feeders 24/7. Consider a larger humid nest upgrade and more outworld space; optional supplemental heating speeds growth (but don't overdo it).
Diapause is not required for this species.
Care Summary
- Very humid nest environment
- Liquid feeder kept full
- High protein requirements
- A gradient of 75-95°F is ideal
