'Flying bulldog': world's largest bee refound

The world's largest bee -- a giant insect roughly the size of a human thumb -- has been rediscovered in a remote part of Indonesia in its first sighting in nearly 40 years, researchers said Thursday.

Despite its conspicuous size, no one had observed Wallace's giant bee -- discovered in the 19th century by British naturalist Alfred Russel Wallace and nicknamed the "flying bulldog" -- in the wild since 1981, the Global Wildlife Conservation said.

"To actually see how beautiful and big the species is in life, to hear the sound of its giant wings... was just incredible," said Clay Bolt, a specialist bee photographer who snapped the enormous insect.

"My dream is now to elevate this bee to a symbol of conservation in this part of Indonesia, a point of pride for the locals there."
