Host plant notes

The three SA specimens mentioned above were collected from Drooping Sheoak (Allocasuarina verticillata) by Shelley Barker, as stated on the labels, and were taken from the foliage (S. Barker, 2011, pers. comm.).

From Moe, Victoria there is a larval host record for the same plant family, Casuarinaceae, based on three specimens in the Victorian Museum with the label stating 'bred ex Casuarina sticks' (C.G.L. Gooding, NMV T8666 to T8668).
