Spotted on a Casuarina tree were clumps of minute brown pellets stuck to branches. Sticking out from the centre of each clump were casuarina needles. Each clump was about 20 to 30mm wide.

These clumps are coverings of entrances to tunnels in the wood in which the Xyloryctine moth larva resides. The brown clumps are stuck together with silk and are probably chewed-up wood. The larva reportedly collects casuarina needles at night, drawing hem into the opening of the tunnel that it has previously made in the wood. It retires into the tunnel and feeds on the collected needles all day.
