Cave nectar bat
If you have ever eaten durian, thank a bat. This small Southeast Asian fruit bat roosts in caves and feeds at night on the nectar of durian blossoms.
A 2019 study in Sulawesi kept different visitors away from durian flowers and found that the flowers open to bats set far more fruit than those closed to animals or open only to insects, concluding that bats were the crop's main pollinators. The cave nectar bat visited more flower clusters than the much larger flying foxes and stayed longer at each. The researchers put the value of that bat work at roughly $117 per hectare each fruiting season, a strong argument for protecting the caves where these colonies roost.
