Izatha hudsoni is a species of moth in the family Oecophoridae.

[1] The species encapsulates the moth discussed by Edward Meyrick in 1916[2] and George Hudson in 1928[3] but not the species discussed by Arthur Gardiner Butler in 1879.

[1] The holotype specimen is held at the New Zealand Arthropod Collection.

[4] This species appears visually similar to the white forms of I. peroneanella but I. hudsoni has translucent whitish hindwings whereas I. peroneanella has grey hindwings.

[5][6] It can be found in Northland, Auckland, Coromandel, Waikato, Bay of Plenty, Taranaki, Taupō, Gisborne, Hawkes Bay and Wellington.
