Distribution and biology

This species is currently recorded from the Atherton Tablelands in North Queensland ( Fig. 6A ), in the Einasleigh Upland Savanna bioregion. The specimens were collected in January, March, May, June, August and November; hence, the species may be present all year long. In Mareeba, Granite Gorge, all the specimens were collected from small trunks of Erythrophleum chlorostachys Baill. ( Fabaceae ), which is the first recorded host plant of this species ( Fig. 11 ).
