Lymantria umbrosa (Butler, 1881) Hokkaido gypsy moth Yes. Lymantria umbrosa is endemic to Japan (Hokkaido) and Russia (Kuril Islands, potentially Siberia) (Pogue and Schaefer 2007). Yes. Female L. umbrosa are attracted to lights at night and may oviposit on non-hosts (Pogue and Schaefer 2007). As this species was previously considered a subspecies of L. dispar, it is likely that some interceptions attributed to L. dispar from Japan were in fact L. umbrosa. An incursion of this moth into New Zealand is believed to have originated from an egg mass arriving via maritime commerce (Ross 2005). Not listed (Nielsen et al. 1996) Yes. A male L. umbrosa trapped in New Zealand is believed to have originated from an egg mass imported via maritime commerce. This would require the moth to have undergone full development in New Zealand (Ross 2005). It is likely that L. umbrosa could establish and spread within southern temperate areas of Australia where suitable host plants also occur. Yes. Lymantria umbrosa feeds on plants used as amenity trees and ornamental plants in Australian parks and gardens, and commercially valuable fruits (Morus and Rubus spp.). Lymantria umbrosa often defoliates large areas of suitable hosts in Japan (Pogue and Schaefer 2007). Control and management of this species in Australia in commercial fruit crops and plants in urban areas would be costly. Yes
