Calliteara horsfieldii, or Horsfield's tussock moth, is a moth of the family Erebidae. The species was first described by the British entomologist Edward Saunders in 1851, and named in honor of the British naturalist Thomas Horsfield, who traveled southern Asia and published works on zoology from the region. C. horsfieldii can be found in southern Asia, the islands of the northern Indian Ocean, and many parts of south east Asia and Indonesia. It is also sometimes referred to as the Yellow Tussock Moth.
