A dead queen, a pharaoh ant invasion, and a terrarium built to test whether an ant colony can still build a masterpiece.

AntsCanada creator Mikey Bustos has spent years documenting his captive insect colonies on YouTube, but “These WEAVER ANT NESTS Will Blow Your Mind” catches his Asian weaver ants (Oecophylla smaragdina) at their most vulnerable moment. The colony had just survived an infestation by invasive Pharaoh ants and was being relocated into a new, climate-controlled tropical terrarium Bustos calls Vortexia. Then, mid-transfer, he finds a dead queen sitting in the collection.

• The colony is transplanted into Vortexia, a custom-built, climate-controlled tropical terrarium designed specifically for weaver ants.
• Bustos discovers a dead queen among the ants during the move, on top of the prior threat from an invading Pharaoh ant colony.
• Despite the losses, surviving workers immediately begin building the species’ signature leaf nests using living-bridge formations and silk-spinning larvae.

Setting Up Vortexia

Vortexia isn’t a standard glass tank with a heat lamp bolted on — Bustos built it as a climate-controlled tropical environment specifically to replicate the humidity and temperature swings weaver ants get in their native range across Southeast Asia and Australia. The move was meant to give the colony a clean, more spacious start after a rough stretch. Instead, the transfer immediately exposes just how much damage the colony had already absorbed.

The Pharaoh Ant Problem

Before the Vortexia move, Bustos’ weaver ants had been dealing with an intruding colony of Pharaoh ants — a notorious pest species known for infiltrating other colonies’ territory and resources. That threat alone would be enough to destabilize a colony, but the video reveals the damage went further than surface-level territorial conflict.

The Dead Queen

While sorting through the colony during relocation, Bustos finds a dead queen among the ants — a genuine setback for any colony, since queens are the sole source of new workers. He doesn’t dress it up on camera; it’s presented as exactly what it is, a loss the colony now has to absorb while simultaneously adjusting to an entirely new habitat.

Workers form living bridges and tension chains with their own bodies just to pull leaves into position — then hand a silk-spinning larva to another worker, who taps it like a glue gun until the seams disappear.

The Mechanics of Nest Construction

The centerpiece of the video is the nest-building sequence itself. Weaver ant workers physically link together to form bridges and tension chains, using their own bodies to drag living leaves into alignment. Once the leaves are positioned, other workers pick up silk-producing larvae in their mandibles and gently tap them against the leaf edges, coaxing out silk that stitches the leaves into watertight, elliptical chambers. It’s collective engineering with no blueprint and no foreman — just workers, larvae, and leaves.

The Colony Adapts Anyway

What makes the footage land is the contrast: a colony that just lost a queen and fought off a Pharaoh ant incursion still organizes itself well enough to start weaving a new home within its first days in Vortexia. Bustos frames it less as a triumphant recovery story and more as a straightforward demonstration of what weaver ants do by default — they build, regardless of what they’ve just been through.

Anyone who’s followed Bustos’ other AntsCanada builds knows Vortexia is a running project, not a one-off — this is the setup video for whatever comes next as the surviving workers keep expanding those leaf chambers. The real test is whether the colony can raise a new queen line to replace the one it lost, and that’s the thread worth watching for in his next Vortexia update.
