Camponotus xerxes

Sheer size is the appeal of this Persian carpenter ant: it is among the biggest in the genus, so the queen and the commanding majors give a colony real presence in any setup. Despite that scale it stays forgiving, active all year with no hibernation to manage, which makes it an unusually approachable big species for a newcomer. It handles the warm, drier conditions of its Middle Eastern range comfortably and forages by day. A standout pick for a beginner who wants impact without a complex care regime.

A large carpenter ant that runs its workforce on sugars and feeds its brood on insect protein. With no winter pause it feeds all year, so keep nectar available and add prey regularly to fuel those big majors.

★★★ readily · ★★ moderately · ★ occasionally · ✗ not eaten

Raise this large carpenter ant from a test tube and move it on when the first workers carpet the floor. Coming from warm, dry country it suits an aerated nest with only a small damp pocket, so a roomy Ytong or 3D-printed chamber fits, with headroom for the sizeable majors and space added as the colony expands. Keep the arena rim escape-proof using fluon (PTFE), oil, or talc and water. ANTonTOP formicaria and starter kits bring the nest, arena, and barrier together in a single ready set sized for a bigger species.

Built for warm, dry country, hold the nest at 24-28 °C and the arena at 24-30 °C, with nest humidity 50-70% and the arena drier at 30-50%. Warm a single end so the colony can settle along the gradient. No winter rest is required, so keep this species active and feeding the year round.

Founding is slow and then quickens once the first workers are out, building toward several thousand workers including the large majors. It comes as a fertilised queen with workers and brood, already through the toughest early phase.

• Camponotus xerxes is among the largest carpenter ants kept in the hobby, a heavyweight even within a genus known for big species.
• Carpenter ants excavate galleries in wood for shelter but gather food outside, so they hollow timber without eating it.
• A gut bacterium called Blochmannia brews amino acids and recycles nitrogen inside the ants, helping them prosper on a sugar-rich diet.
• They have no sting and defend the nest with formic acid sprayed from the gaster and a powerful bite from the majors.

Is Camponotus xerxes good for beginners?

Yes. It is rated Beginner and needs no hibernation, a forgiving choice that still gives you a big, eye-catching colony.

Does this giant carpenter ant need a winter rest?

No. Hibernation is not required, so keep it active all year.

Does it sting or bite?

No sting; only a mild bite.

How big can the colony get?

Several thousand workers over time.

How big is the xerxes queen?

The queen is large at 17-20 mm.

How fast does it grow?

Slow at first, then faster as the first workers mature.

What does it eat?

Sugar water and nectar for energy plus crickets and flies for protein.

Will it arrive alive?

Colonies ship with queen, workers, and brood plus a heat or cool pack, sent within 24 h with tracking.

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.
