Bats have a bad reputation because of their nocturnal nature and their association with vampires. However, did you know that bats are harmless, and that they represent 20% of all mammal species in the world! There are about 1240 species of bats the world over. They play vital ecological functions such as flower pollination and dispersal of seed, and what’s more, they help control insect population by eating them, which can also go a long way to reduce the need for pesticides. So overall, bats are valuable and useful creatures.
