Poinciana Longicorn Beetle
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.

This species is found in rainforest and open forest in eastern Australia. It is common in Queensland and New South Wales and also occurs on Lord Howe Island. The larvae are huge white grubs found in rotten wood, especially dead Poinciana or fig trees. It is an important pest of pecan trees. The large adults sometimes blunder into house lights.
