Nyctemera amicus is a fairly common visitor to the moth light, and as the first name suggests, the larval food plants include the Groundsels or Fireweeds, Senecio species, as well as certain other plants in the Asteraceae. A random glance upwards recently was rewarded by the sighting of this mating pair on the house eave lining, the male is recognisable by the broader pectinations of its antennae. For photographers reading, the RAW Nikon NEF file was processed in the highly recommended free open-source RawTherapee program to produce the jpeg image below.
