Species Info:

Cyclommatus speciosus is a notable stag beetle species native to Vella Lavella Island in the
Solomon Islands. It is recognized for its impressive size and distinctive features.

This beetle can grow up to 55 millimeters in length. The Vella Lavella stock of Cyclommatus
speciosus is particularly notable for its aggressive-looking mandibles and the absence of yellow highlights on the femurs, distinguishing it from the Malaita Island locality.

Development and Breeding:
Cyclommatus speciosus is known for its rapid development compared to other stag beetle
species. It has one of the fastest development times in captivity, taking just 4 to 6 months from egg to adult, whereas most stag beetles typically require 1 to 2 years. This makes it a popular choice among enthusiasts for breeding.

In its natural habitat on Vella Lavella Island, the beetle's larvae feed on decaying wood, which is crucial for their development. Adult beetles have a diverse diet that includes fruits such as banana, apple, pear, peach, and watermelon. This diet is also reflected in captive care, where they are provided with a variety of fruits to maintain their health and vitality.

The Vella Lavella stock is genetically distinct from the Malaita Island stock of Cyclommatus
speciosus. The two populations should not be cross-bred due to their genetic differences and morphological variations. The Vella Lavella beetles have more aggressive-looking mandibles and lack the yellow highlights found on the femurs of the Malaita stock.

The Vella Lavella stock of Cyclommatus speciosus has been successfully bred in captivity,
making it a well-studied and popular species among collectors. Its rapid development time and distinctive appearance add to its appeal in the hobby

In summary, Cyclommatus speciosus from Vella Lavella Island is distinguished by its aggressive mandibles, lack of yellow highlights on the femurs, and its impressive size of up to 55 millimeters. Its rapid development and specific dietary needs make it a unique and intriguing species for beetle enthusiasts.
