Rhyncogonus caudatus Van Dyke

Tailed Rhyncogonus Weevil (Rhyncogonus caudatus)

This species is endemic to the island of Huahine, where it can be found on the leaves of several non-native and native plants, including nahe (Angiopteris evecta (G. Forst.) Hoffm.).

The animals are black in colour and bear some larger, white scales on the sides of the head, the body, and above all, the abdomen, where they build some kind of a short process.

The males reach a length of about 1,15 cm, the females, with 1,4 cm, are distinctly larger. [1]
