The Galapagos Carpenter bee is the only bee found in Galapagos and is found nowhere else in the world. It is a solitary species, the males being smaller and a yellow-brown colour and the females being larger and black in colour. The females are more common than the males and both genders are found on Isabela and Floreana. They nest in dead wood boring a 1 cm wide tunnel where they lay a single egg and feed the larva on nectar before it pupates.
