Grafton Gully at Symonds St Cemetery, Grafton, Auckland. Larvae on lower surface of Ganoderma.
Single specimen flew into our house and created a mud coccoon on a piece of fabric.
A nest chamber got knocked off a house wall, so I opened it for a look. Spiders inside were two salticids, theridiids and maybe tetragnathids. The spider at bottom with dark abdomen has a wasp grub on its back. The larger of the two salticids (top right) is 4mm long.

The large sand scarab grub appears to be being attacked by the wasp.
Two males going at it!
Three-chambered nest, shortly after completion and sealing of the middle chamber.
