Seven species of bees native to Hawaii have been granted endangered status. These are the first species of bees to be given that status by the US Fish and Wildlife Service. These species are all called yellow-faced bees. Yellow-faced bees are the only bee species that is native to the island. They look similar to wasps. Yellow-faced bee populations have been declining across Hawaii. This decision echoes concerns around the world about bee populations. In total, 40 percent of bee species are thought to be facing extinction. This is especially concerning because bees pollinate approximately 75 percent of our crops.
