These caterpillars have been found feeding on
On Wattle: the caterpillars initially are yellowish brown, which provides them with great camouflage amongst the Wattle flowers.
Later caterpillars develop a pale edged dark line along the back.
The adult moth is a variable grey or brown, sometimes with a broad pale band across each wing.
The wingspan is about 2 cms.
The eggs are oval, pale brown, and laid separately.
The species has been found in :
as well as in Australia in
A number of subspecies have been proposed for the various forms of the adult moth, including albiplaga (L.B. Prout, 1958) and irregulata (L.B. Prout, 1958).
The variability of this moth overlaps with the variability of Chloroclystis pallidiplaga, so that often they cannot be distinguished.
