[2] It has also been collected in Auckland, Tauranga, Tolaga Bay, Napier, Taupō, Paiaka, Milford Sound, Westport, Haast, Kaitorete Spit, Portobello and in the Catlins.

[2][4] The larvae feed on Ammophila arenaria (also known as marram grass), Acaena novae-zelandiae and Calystegia soldanella.

[4] It has been hypothesised that the larvae are nocturnal, coming out at night to feed on the stems and leaves of their hosts.

[4] Although marram grass is now generally considered to be an invasive species in New Zealand it is now one of the main host plants of this endemic moth.

[4] It has been suggested that prior to removal of this invasive grass a survey for the presence of A. innominata be conducted.

[4] This regarded as especially important in more southerly coastal regions as the brachypterous nature of the females of this moth hinders the spread of populations.
