Scots pine
The larvae feed on a wide range of plants in New Zealand including southern beech ("Nothofagus" spp.), podocarps and kanuka ("Kunzea ericoides"). They also feed on European gorse ("Ulex europaeus"). Some of the Cornish larvae initially fed on Leyland cypress ("Cupressus" × "leylandii") and were moved to Scots pine ("Pinus sylvestris") in the second instar when they became unhealthy. They also fed on box ("Buxus sempervirens") and yew ("Taxus baccata") but preferred Scots pine.
