They are most frequently encountered perching along the forest edge on the tops of leaves with the wings half open or nectaring on a variety of flowers, including Eupatorium, Daucus, Palicourea, Tournefortia, Urera, Senecio and Canna species.
On 17 March 2006, Inchbonnie was the location for the release of insects in an attempt to eradicate the ragwort weed from the West Coast.
Several other rare plants found their shelter here, such as: Milk-vetch (Astragalus exscapus), wind flower (Pulsatilla pratensis), sage (Salvia austriaca), Herbaceous Periwinkle (Vinca herbacea), Golden Ragwort (Senecio doria).
The slow-flying moths can often be seen feeding at flowers; it is common around its preferred food plants of the daisy family, for example groundsel (and other Senecio spp.), ragworts and Cineraria.
