A “flying bulldog” is how conservation photographer Clay Bolt described it, while local people call it raja ofu, or the king of bees. Wallace’s giant bee (Megachile pluto) is certainly a bee-hemoth. The world’s largest species of bee, it can grow to four times the size of a honeybee, with a wingspan of 64mm (2.5in). Such a giant should be hard to lose, but the incredibly rare bee, native to a cluster of Indonesian islands, was feared extinct for nearly 40 years, until Bolt and his colleagues “rediscovered” it in 2019.
The naturalist Alfred Russel Wallace, a contemporary of Charles Darwin, collected the first known sample of the bee in 1858 while exploring Bacan, one of northern Indonesia’s Maluku (Moluccas) islands. Wallace collected a single female of the species, and noted it as “a large, black wasp-like insect, with immense jaws like a stag-beetle”.
