Formica neogagates Species Introduction
Claustral. She needs no food during founding. What sets this one apart is that mature colonies are polygynous, so a queen count above one later is normal rather than a sign something has gone wrong. Whether they will co-found from the start is not established for this species, so we recommend founding singly and combining later if at all.
A small, fast, unassuming Formica with an enormous range: coast to coast across southern Canada and the northern states, down the Appalachians to North Carolina, and south into northern Mexico. In Nevada it turns up between 3,900 and 10,000 feet across cool desert, pinyon-juniper, conifer forest and alpine ground. Nests are in soil under stones and logs, with entrances of only 2 to 3mm. Workers are monomorphic, colonies are small and the ants are timid, though a populous nest will produce workers that bite promptly. They tend mealybugs and coccids for honeydew. The remarkable part is what lives off them: this is a host for six slave-making Formica and for Polyergus mexicanus.
A small, quick, modest field ant for a keeper who likes an ant with a story rather than a spectacle. Colonies stay small and the workers are timid, so do not judge this one by the size of the crowd in the outworld. Two things end colonies here. The nest going dry is the first, because the brood sits in damp soil in the wild and has nowhere else to go in a formicarium. Skipping the winter is the second, and with a range reaching southern Alaska that is a decision to make deliberately.
Formicarium
Soil nesters that tuck the nest under a stone or a log, so a Substratum Sand Ant Nest or any substrate nest that holds moisture is the right call. Wild nest entrances are only 2 to 3mm, which tells you how little opening they actually need. Seal the fittings properly, keep a fluon barrier current, and give them ground rather than height.
Water & Humidity
Moderately humid. In the wild the nest sits in soil under a stone where moisture holds while the surface bakes, and collections include riparian ground and damp salt-crusted flats. Keep most of the nest damp with a drier, warmer corner for pupae. A nest that runs dry end to end is one of the two ways we lose these.
Recommended to use TrapJaw Labs PVA sponges during founding for improved success rates and more nanitics. Keep the tube charged right through, as this species wants damp ground at every stage.
Keep a liquid feeder with water (distilled, purified, or spring) in the foraging area at all times. Fast foragers get through more water than their colony size suggests, and a properly damp nest does not remove the need for a feeder.
Protein
Protein leads for this genus. Formica are scavengers and hunters before they are anything else, and neogagates takes insect prey and carrion readily. Offer protein two to three times a week and scale it to the brood pile rather than to the worker count, since colonies stay small but can carry a lot of brood for their size.
TrapJaw Labs feeds our F. neogagates colonies with pre-killed D. melanogaster and D. hydei fruit flies, cockroach nymphs, and sliced mealworms. They are timid feeders, so put items down and step away rather than hovering. A colony that will not approach is usually a colony being watched.
Two to three times per week. Increase amounts to scale with brood development.
Carbohydrates
Carbohydrates matter, but they come second here. In the wild these ants tend mealybugs and coccids for honeydew rather than working a nectar source hard the way the sugar-driven genera do. We recommend providing sugar-water (we use our Ant Nectar Mix) and fresh-water liquid feeders in the outworld at all times.
Occasional small honey drop in the outworld is fine. They take it without much urgency compared with the sugar-obsessed genera, so keep it occasional rather than standing.
Keep a feeder stocked, but do not read a slow drawdown as a problem. This is not a genus that empties one overnight.
Maintenance
Week 1: Settle the founding queen somewhere dark and undisturbed and offer no food. Keep the sponge wet. If you have several queens from one flight, found them in separate tubes rather than together, and revisit combining once each has workers of her own.
Weeks 4–6: First workers ('nanitics') appear. Start protein two to three times a week straight away and put out a sugar feeder. Expect a small, nervous colony that scatters when you open the setup. That is normal for this species rather than stress you need to fix.
Months 2+: Growth is steady and the colony stays modest. Move them up at about 75% of the nest space in use, keeping the new nest damp from the day they go into it. If a wild-collected colony ever produces workers that do not match the rest, look hard before assuming a variant, because this species hosts a long list of parasites.
Diapause may be required for this species. Formica neogagates runs from southern Alaska to northern Mexico and from 3,900 to 10,000 feet, so what a colony needs follows where it was collected rather than the species. Northern and high-elevation stock should get 12–16 weeks from October at 40–50°F. Southern low-elevation colonies can take 6–8 weeks or less. Remove supplemental heat but keep liquid food and water sources fully-stocked, and keep the nest damp while it is cool.
Care Summary
- Protein leads, 2–3×/week, scaled to the brood pile
- Nest damp with a drier corner for pupae, NEVER dry end to end
- Diapause length follows where the queen was collected
- Gradient 72–86°F, and the cool end matters
- Sugar feeder stocked, but they use it slowly
- Small, timid colonies are normal, not a problem
