Synemon parthenoides, the orange-spotted sunmoth or link moth, is a moth in the Castniidae family. It is found in Australia, including Victoria, Western Australia and South Australia.[1]
The wingspan is about 35 mm for males and 44 mm for females. The upperside of the forewings is blackish-grey, with small black and white markings that are more pronounced in the females. The undersides of the forewings are boldly patterned in black and orange and have a few obscure whitish markings toward their apices. The upperside of the hindwings is black with bright orange spots and markings. The hindwing undersides are similar except that there are also a few indistinct whitish markings near their apices.[2]
The larvae feed on the tussocks of Lepidosperma carphoides. They are pale pink.
