Proformica nasuta

The draw here is the visual variety within a single nest. Workers of this species span a wide size range, so the colony never looks uniform, and against a large queen the contrast is easy to enjoy. It ranges across Spain, Mediterranean Europe and into the Middle East, thriving in hot, dry conditions that suit a desert-edge setup. Holding more than one queen helps the population climb quickly, and with no sting and only a mild bite the outworld is easy to work in. Rated Intermediate, it asks for warmth and low humidity but only a light winter pause, which keeps its yearly care manageable.

A dry-country omnivore: the foragers run on sugars and stored liquid food, while insect protein feeds the growing brood. Keep nectar on offer at all times and add insects through the active season.

Found the colony in a test tube and upgrade to a larger nest as it grows. This desert-edge ant runs dry, so favour a well-aerated nest, Ytong, plaster or aerated concrete, that you keep on the dry side rather than wet, with just a faint moisture gradient toward the brood. Give the foragers a generous, sandy outworld to range across. Contain them with a fluon (PTFE) band, a thin oil line, or talc and water along the rim. ANTonTOP formicaria and starter kits bring a matching dry nest, arena and escape barrier together as one tidy set.

Run this desert-edge ant warm and dry. Keep the nest at 22 to 26 C and the arena at 24 to 30 C. Humidity stays low to suit it, 40 to 55% in the nest and just 25 to 45% in the arena. Heat one side for a gradient so brood can be placed in the warmth. It takes only a light diapause, a brief cool rest; the colony may slow, but keep feeding and skip any deep cooling.

Growth is moderate and picks up noticeably when several queens are laying together, the shared output carrying the colony toward as many as 1,000 workers over time. Early on the pace is gentle, then it builds. You receive a queen, or more than one, with workers and brood, packed for transit and ready for a dry, warm founding setup.

• Proformica nasuta workers vary widely in size within a single nest, a polymorphism that lets the colony cover everything from brood care to foraging in harsh open ground.
• The genus stores liquid food in distended workers, a honeypot-style strategy for surviving long dry spells.
• Proformica nests are the target of Rossomyrmex slave-makers, which depend on capturing Proformica brood to maintain their own colonies.
• These ants thrive on hot, arid steppe from Iberia eastward, foraging across ground too dry for most temperate species.

Is Proformica nasuta good for beginners?

It is rated Intermediate; the no-sting biology helps, but the dry, warm requirements suit a keeper with some experience.

Does Proformica nasuta need a winter hibernation?

Only a light diapause, a brief cool rest; keep feeding and do not lower the temperature sharply.

Does this Mediterranean ant sting or bite?

No, it has no sting, only a mild bite.

How big do colonies get?

Up to 1,000 workers, with polygyny helping early growth.

How big is the queen, and how varied are the workers?

The queen is 9-11 mm, with workers ranging 3-10 mm.

How fast does it grow?

Moderate, picking up pace when more than one queen is laying.

What does this dry-country ant eat?

Sugar water and nectar for energy, plus insects such as crickets and flies for protein.

How is it shipped?

As queen(s) with workers and brood, with a heat or cool pack, sent within 24 h with tracking for 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.
