[2] The adults are a rich reddish yellow colour giving rise to the vernacular name golden spider wasp.

Hunting females mainly use vision but antennal chemoreception plays some role.

The female wasp holds the prey spider by the chelicerae and walks backwards, dragging it dorsum uppermost.

After the female has laid eggs on the spider she fills a 20–27 mm length of the cell-passage with compacted earth.

[3] Native to Tasmania and south-eastern Australia, introduced to New Zealand where they are now found from the North Cape to Auckland.
