The small flying fox, island flying fox or variable flying fox (Pteropus hypomelanus) is a species of flying fox in the family Pteropodidae. It is found in Australia, Cambodia, Indonesia, Malaysia, the Maldives, Myanmar, Papua New Guinea, the Philippines, the Solomon Islands, Thailand, and Vietnam.

The small flying fox is quite variable in its colouring. The head is usually dark brown but can be yellowish-brown and is paler in the eastern part of the animal's range. The back is tawny-brown and the underparts some shade of buff. The ears are partially furred and the wing membranes are black. The fur is short on the back and medium-length on the underparts. This bat can be distinguished from the rather similar Ryukyu flying fox (Pteropus dasymallus) by the fact that its tibia are bare rather than covered with fur.

The small flying fox is native to islands in the Indo-Pacific region. Its range includes the Maldives, the Andaman Islands, the Nicobar Islands, Melanesia, the Philippines, Indonesia, Papua New Guinea and the Solomon Islands. It is found at altitudes of up to about 900 metres (3,000 ft). In many parts of its range it roosts in small outlying islands and flies to larger bodies of land to forage at night.

The individuals in this gallery were seen at Koh Chiang eastern Thailand and in the poacher nets in Koh Lanta, in front of my home.
