Biology, Spatial Distribution and Range Expansion of Acraea terpsicore (Linnaeus, 1758) (Nymphalidae: Heliconiinae) in Borneo

The Tawny Coster, Acraea terpsicore (Linnaeus, 1758) is one of the prominent species from the tribe Acraeini, which is widely distributed throughout the Indian and Sri Lankan region. In the past three decades, its distribution range has expanded southwards through Southeast Asia and Australia. This...
