Wallace’s giant bee, first discovered in 1859 on three remote islands in Indonesia, has been a particularly elusive bee. Long thought extinct, it was not seen again until 1984, 125 years later. Now for the first time a film crew has filmed it alive in the wild.

At 1.5 inches long, and with a wingspan of 2.5 inches, Wallace’s giant bee dwarfs’ other bees. It has a distinctive sound made by its wings, a “deep, slow thrum that you could almost feel as well as hear.” Wallace’s is a solitary bee with the unusual habit of living in termite nests. We don’t know what its sting is like because no one has been stung by one, so far. It fortunately appears not to be aggressive.
