Megabat Diet: What Do Megabats Eat?

Frugivores and Nectarivores of the Tropics

Megabats are almost exclusively herbivorous, primarily eating fruit, nectar, and pollen. This diet distinguishes them sharply from most microbats, which feed predominantly on insects. The megabat diet is closely linked to their ecological importance as seed dispersers and pollinators in tropical forests.

Fruit (Frugivory)

The majority of megabat species are frugivorous — fruit is their primary food source. Throughout the family Pteropodidae, a diverse array of fruit is consumed from nearly 188 different plant genera. Favored fruits include figs, mangoes, guavas, papaya, and many wild tropical fruits. Megabats can consume up to 2.5 times their body weight in fruit per night.

Frugivorous megabats serve a critical ecological function: seed dispersal. They carry fruit away from parent trees and either spit out seeds or defecate them after digestion. This aids forest regeneration, particularly for large-seeded trees that cannot be dispersed by wind.

Nectar and Pollen (Nectarivory)

Many megabat species are nectarivorous — they feed on flower nectar and pollen. Species with long, brush-tipped tongues (such as blossom bats and long-tongued fruit bats) are especially adapted for this diet. In Australia, Eucalyptus flowers are a particularly important nectar source. The relationship between bats and the plants they pollinate is called chiropterophily.

• Fruit from 188+ plant genera — figs, mangoes, wild tropical fruits
• Nectar from eucalyptus, banksias, baobabs, and sausage trees
• Pollen — consumed while feeding on flowers, inadvertently collected
• Leaves, shoots, bark — supplementary for some species

Sense of Smell and Taste

Megabats have extraordinary senses of smell to locate food — their olfactory abilities rival those of domestic dogs. Tube-nosed bats have stereo olfaction, allowing them to follow scent plumes three-dimensionally through dense forest. Megabats also possess the TAS1R2 gene, giving them the ability to taste sweetness, helping them identify ripe, energy-rich fruit.

Conservation & Further Reading

Megabats face significant threats from habitat destruction, hunting, and climate change. A quarter of all Pteropodidae species are listed as threatened by the IUCN. Their low reproductive rates mean that population recovery is slow after decline events. Supporting tropical forest conservation is the most effective way to protect megabat diversity.
