Anilara subcostata  Distinctive features

Dark grey-black coloration sometimes with weak bronze reflections; elytra usually bearing two very weak ridges or 'costae'; sides of pronotum very rounded; hind tarsus in male with gibbous first segment (as in Anilara adelaidae and allied species).

Notes

Blackburn probably based his descriptions on specimens at the SA Museum collected by Tepper from Ardrossan, Nuriootpa and Cooke Plains (c. 17 km SE of Tailem Bend). Only the latter is labelled as a type. It was collected by Tepper on 5 Jan 1887 from a 'shrubby Acacia'.

Although emerged adults have been seldom encountered, breeding records and observations by me and A.M.P. Stolarski show this to be a very common and widespread Buprestid in both mallee and woodland habitats of SA. Its larval host plants are often riddled at their base with frass-filled tunnels and there is a high level of mortality with dead non-emerged adults being quite common in some populations.

 *Inferred when a site has counts of active beetles for each of two consecutive periods (date ranges), one finishing and the other starting in the same quarter-month.
The count estimate is assigned to that quarter-month and calculated as the lower of the two total beetle counts, divided by the number of quarter-months in its date range.

Host plant notes

Adults have been collected from a range of hosts in various plant families but do not seem to associate with the foliage of their larval host plants. On the other hand, breeding appears to be confined to shrubs of the plant family Rhamnaceae, and is concentrated in the hard, woody basal stems and upper root-stock.
