Izatha attactella
Izatha attactella is a moth of the family Oecophoridae. This species is endemic to New Zealand, where it is known from both the North and South Islands as far south as mid-Canterbury. Larvae of this species feed on the soft inner surface of the bark of dead trees and shrubs. Adults have been recorded from September to December. Taxonomy. This species was first described by Francis Walker in 1864 from specimens obtained by Colonel D. Bolton in Auckland and Mr Sinclair. The lectotype specimen is held at the Natural History Museum, London. In 1888 Edward Meyrick, thinking  he was describing a new species, named this moth "Semiocosma platyptera". The lectotype for this description was collected by George Hudson in Wellington and is also held at the Natural History Museum, London. In 1915 Meyrick synonymised this name with "I. attactella". This synonymy was upheld by Robert J. B. Hoare in 2010. Hudson discussed and illustrated the species in his book "The butterflies and moths of New Zealand". Alfred Philpott studied and published on the male genitalia of this species in 1927. Description. Hudson described the larvae of this species as being about in. long when fully grown. The  head is dark brown and shiny while the body is white. The pupa is pale ochreous in colour with a brown tinge to the head and lower portion of the pupa. It is enclosed in an oval cocoon made from silk and pieces of chewed bark. Walker described the adults of the species as follows: The wingspan 24.5–38 mm for males and 22–36 mm for females. "I. attactella" resembles "I. voluptuosa" but can be distinguished from the latter by having a narrow forewing, a paler hind wing, more obvious scale tufts and a longer dark basal streak. "I. attactella" is  also on the wing earlier in the season in September to December with "I. voluptuosa" being present in the later months of November to February. Distribution. This species is endemic to New Zealand. "I. attactella" is widespread and present in both the North and South Islands but in the latter only as far as mid Canterbury. This species has been recorded in the following locations: Northland, Auckland, Coromandel, Waikato, Bay of Plenty, Taranaki, Taupo, Hawkes Bay, Rangitikei, Wellington, Marlborough Sounds, Nelson, Buller, Marlborough and mid Canterbury. Behaviour and life cycle. Pupation takes place under the bark in the above described  oval silk and chewed wood cocoon. Adults are on wing from September to December. However, in the South Island occasional specimens appear in December and January. When reared in captivity in the North Island this species emerges from July onwards. This species does not come readily to light in large numbers. Habitat and host species. Larvae have been reported feeding under the bark of dead "Elaeocarpus dentatus", "Aristotelia serrata", "Nothofagus", "Myoporum laetum" and "Rhopalostylis sapida." Larvae feed on the soft inner surface of the bark. This species has also been recorded from dead wood of "Castanea", "Litsea calicaris", "Olearia paniculata , Pinus patula", "Pinus radiata" and "Sophora" species. In Auckland, larvae have been recorded as feeding on dead rotten wood lying on the ground.
