The adult host plant is Leptospermum polygalifolium polygalifolium, and at least as regards that particular plant it was photographed on is in peak bloom (which is also important to record), and the concatenated locality is probably best described as 'Oallen Ford, 2.44 km N of Oallen' (distance measured using Google Earth which plots the exact location of Oallen, and measures the distance and 16-point compass direction therefrom using the Vincenty formula). A very interesting locality as Stuart's observations at this site of the previous day and today adds a useful intra-range location between the recent sighting near Borough and its haunts to the NE. Cheers, Allen M. Sundholm OAM.

I concur with MarkH - this is Castiarina livida. In this photo it is amongst (this species likes to bury in arse up) the flowers of is both adult host plant (general knowledge amongst aussie buprestid enthusiasts but apparently unpublished) and a larval host plant (by myself and R. de Keyzer, unpub.), being Ozothamus diosmifolius. Adults do occur on other adult host plants, su h as Leptospermum spp., but most often occur on Ozothamus diosmifolius. Cheers, Allen.

Hi Christine, currently I see two pictures in your post above, and both are of Castiarina interstitialis. Was there a third photo you split off, being of Castiarina sexplagiata? Cheers, Allen.
