Monomorium floricola

The biology here is what makes Monomorium floricola so interesting to keep. Its queens are wingless, so the colony spreads by budding rather than launching nuptial flights, and a single setup can divide and grow in a way few hobby ants do. Multiple queens push the colony to large numbers of minute, fast workers. It is a pantropical species recorded from India and across the tropics, so it needs steady warmth and humidity. Unusually for such a small ant it is not light-shy and stays active in daylight, though its size and habits call for a careful keeper.

A minute omnivore. The slender workers patrol for sugars and carry small insect prey home for the brood, so keep sugar available at all times and offer protein regularly.

Start this tropical tramp ant in a test tube and check the seal closely, since hairline gaps are enough for it. When workers cover the floor, shift them to a humid plaster or acrylic nest with a perfectly gas-tight fit and a slightly drier arena. Growth can be brisk, so upgrade and add modules in good time. Keep a fresh fluon (PTFE) barrier on the arena and renew it regularly; oil or talc-and-water are backups. ANTonTOP formicaria and starter kits pair a snug nest with an arena and barrier so a fast-growing colony stays contained from the start.

A tropical ant through and through: nest 24-27 °C, arena 25-29 °C, with a humid nest of 60-75% and an arena of 50-65%. Warm one side only to give the colony a warm-to-cool gradient. As a tropical ant it takes no hibernation and stays active year-round; just keep it fed and warm.

Once established this polygyne colony grows fast and can reach up to 100,000 workers, with new nests budding off rather than waiting on flights. You receive a fertilised queen with workers and brood, often with more than one queen.

• Known as the bicoloured trailing ant, it is one of the most widespread tramp ants on Earth, carried around the tropics by human trade.
• Its queens are wingless, so the colony has no nuptial flight and instead spreads by budding off new nests.
• Unlike many tiny ants, the workers are not shy of light and will forage openly in daylight.
• The slender, two-tone workers often nest above ground in plant stems and leaf litter rather than in soil.

Is Monomorium floricola good for beginners?

It is rated Intermediate, chiefly due to its minute size and escape risk; best after some experience.

Does it need hibernation?

No, it is tropical and needs no hibernation. Keep it active year-round with steady feeding and stable temperatures.

Does this tiny pantropical ant sting or bite?

It has a sting and a mild bite, but its tiny size makes it harmless to keep.

How big can the colony get?

Up to 100,000 workers, helped by multiple queens and budding.

How large is the queen?

The queen measures 5-6 mm and workers just 1.5-2 mm.

How fast does it grow?

Fast, as a warm-loving polygyne species that multiplies by budding.

What does Monomorium floricola eat?

Sugar water and nectar or jelly readily, plus small insects for brood; it does not take seeds.

How is it shipped and will it arrive alive?

It ships as a queen with workers and brood, with a heat or cool pack, dispatched within 24 h with tracking for a safe live arrival.

Escape prevention. Coat the inner rim of every open arena with fluon (PTFE), or use talc-and-water or an oil barrier as a backup, and keep a tight, fine-mesh lid on top. Check the barrier regularly, since dust, condensation and feeding debris break a fluon line over time. Keep tubing connectors tight and seal any gaps in the nest.

Keeping reminders. Always offer fresh water and never let the nest dry out completely. Give carbohydrates continuously and protein a few times a week, and remove uneaten insect prey within 24 hours before it moulds. Keep the formicarium out of direct sunlight and away from constant vibration, which stresses a young colony. A water-filled test tube plugged with cotton makes an ideal spare incubator whenever you need one.

Before you buy – do not rehouse too early. Have a test-tube setup or a small formicarium with an outworld and a working barrier ready before your colony arrives. A founding colony grows slowly at first, which is normal. Moving a small colony into a large nest too soon invites mould, mites and stress, and the workers die off one by one. Keep the colony in its open test tube on the arena, plug the nest entrance with cotton, and open up the next chambers only once the colony fills roughly 10-15% of the space.

What we ship. Every colony ships with a live-arrival guarantee, backed by our 24h unboxing-video guarantee: if the queen does not arrive alive, we reship free. Parcels travel with DHL, InPost (PL) or EMS, with a heat or cold pack to suit the season, packed discreetly and securely. We ship across the EU and worldwide, with free shipping over the Europe threshold.
