Macrodontia cervicornis - Our Planet
Macrodontia cervicornis is one of the largest beetles, with known specimens exceeding 17 cm in length. Part of this length is due to the enormous mandibles, from which it derives both of the names in its binomen: Macrodontia means "long tooth", and cervicornis means "deer antler". It is also known as the "Sabertooth Longhorn beetle". Most of this species' life is spent in the larval stage, which can last up to 10 years, and the larvae of M. cervicornis are extremely large, reaching up to 21 cm in length. Macrodontia cervicornis is known from the rain forests of Colombia, Ecuador, Peru, Bolivia, the Guianas, and Brazil. Additional described species in the genus extend the overall range of the genus from Guatemala to Argentina.
