Tiger Moth Amata sp. from South Sarawak around 600m ASL, probably Amata prepuncta Holloway, 1988

Without a clear view of the abdomen and hindwings, it is very difficult to determine the species. It could be also:

Amata tetragonaria Walker, 1862
Amata macroflavifer Holloway, 1988
Amata borneogena Obraztsov, 1955
Amata kinensis Hampson, 1898
