A large longicorn (longhorned) beetle about 55 mm long with pale pearly brown smooth elytra. A darker brown thorax was textured with small depressions and short lateral spines. Antennae appeared to be a little longer than half the body length. The beetle's mandibles were prominent.
Flew into the lights outside our cabin and kept flying around the lit area - A riverside caravan park.
The largest longicorn beetle I've seen.
Seen in Queensland, NSW and Lord Howe Island where Poinsiana and fig trees are in abundance. Fat white larvae of this species can be found in dead wood of these trees.
The antennae in this species is said to be longer than the body but this beetle's antennae was surprisingly shorter.
