How to recognize it

Slender black ants with large eyes, long toothed mandibles that point forward and are reddish-brown like the legs, and a reddish tip on the gaster. All workers are the same size and the queen differs only by a bulkier thorax, while the Indian jumping ant (Harpegnathos saltator) has a reddish thorax and this species has a black head and thorax.

Why this rating

  • Makes it easier: No hibernation to manage
  • Makes it harder: Curious workers: keep an escape barrier on the outworld
  • Makes it harder: Semi-claustral: the founding queen has to be fed
  • Makes it harder: Needs constant warmth all year round
  • Makes it harder: The workers can sting

Notes from keepers

  • Watch out

    Offer only live prey. In a field test the workers did not attack cockroaches killed with boiling water, and most keepers report that colonies ignore dead insects. Small live crickets or cockroach nymphs work, some keepers remove the hind jumping legs of the crickets so the ants can catch them, and if the colony ignores one species, try another: one colony refused house crickets but carried a different cricket species straight into the nest.

  • Tip

    Give the nest steady warmth and moist chambers, and keep the arena drier. Keepers who relied on cool room temperature report slow brood and pupae opened and eaten before hatching, while most recent reports of healthy colonies use a heated nest or a warm room.

  • Watch out

    Mites are a recurring killer in the keeping reports, and they can arrive with a shipped colony or on feeder insects. Buy feeder insects from a clean source, check the workers under a magnifier, and avoid a soggy setup, because wet nests and arenas with leftovers are where mites thrive.

  • Watch out

    Expect a shaky start. Shipping is hard on these ants, and some colonies lost most of their workers in transit. Colonies also often arrive with two or three queens, and the dominant one may expel or kill the others once the first larvae hatch, so leave the colony undisturbed until it settles.

It hunts alone and by sight. A worker stays still and quickly shakes her gaster, then jumps onto the prey, clamps it with her mandibles, curls her gaster under it and stings it for about ten seconds to paralyze it before carrying it home. Keepers report jumps of up to about 10 cm, and the ants also leap away when startled, so keep the lid closed while feeding.

Some can, but much less than in the Indian jumping ant. In Harpegnathos saltator, each colony has a single queen, and mated workers called gamergates take over egg laying when she is lost. In a study of H. venator nests in northern Thailand, mated workers laid eggs in only a few colonies that still had a queen, and colonies run only by mated workers were rare. Workers also lay unfertilized trophic eggs that serve as food.

In northern Thailand the nests had a chimney-like entrance with a funnel about 3 cm wide, leading to two or three chambers with flat, smooth floors that the ants decorated with fragments of old cocoons. They are usually dug into soil or clay on shaded banks, which is why keepers use plaster, Ytong or moist loam nests.

Harpegnathos venator workers measure 14–18 mm, and the queen measures 16–20 mm.

One or more. Harpegnathos venator colonies are usually founded by a single queen, but many end up with several queens living together.

Yes. Harpegnathos venator workers can sting. It is usually mild for people, but it's best to avoid handling them.

Keep the Harpegnathos venator nest at 24–28 °C, with 60–80 % humidity in the brood chambers.

No. Harpegnathos venator stays active all year and does not need a winter rest.

Harpegnathos venator is not on the EU list of invasive alien species and is not protected in the countries we checked. Rules differ between countries and can change, so check your local laws first.
