Spilosoma canescens, the Dark-spotted Tiger Moth or Light Ermine Moth, is a moth in the family Arctiidae that is found across most of Australia. The larvae are polyphagous, and are known to feed on Bidens pilosa, Helianthus annuus, Taraxacum officinale, Alcea rosea, Rosa odorata, Plantago, Ricinus communis and Tradescantia albiflora. The polyembrionic parasitoid wasp Copidosoma floridanurn sometimes uses this species of caterpillar as a host.
