Megachile Pluto, the World's Largest Bee originating from Indonesia

Megachile Pluto is a very large bee found in Indonesia (bees that use resin to create a compartment in the nest). able for females 39 mm (1.5 ") with a wing length of 63 mm (2.5"), Megachile Pluto was regarded as the world's largest bee, and also known as Wallace's Giant Bee. whereas males only grow about 23 mm (0.9 ").

Megachile Pluto was first discovered in Indonesia in 1859 by the naturalist Alfred Russel Wallace. This was considered extinct until rediscovered in 1981 by Adam C. Messer, an American entomologist, who found six nests on the island of Bacan and nearby islands other.

Megachile Pluto build their nests in active termite nests, which explains why the islanders did not even know the existence of these bees.
