Disterna

Disterna is a genus of longhorn beetles belonging to the family Cerambycidae, subfamily Lamiinae. These beetles are primarily found in Australia.

The genus is characterized by its distinctive morphology, generally featuring an elongated body shape typical of longhorn beetles. Adult Disterna beetles are often observed on various types of vegetation, where they feed and mate. The larvae of Disterna typically bore into wood, contributing to the decomposition of dead or decaying trees.

Several species are recognized within the Disterna genus. Species identification relies on detailed examination of physical characteristics, including body size, coloration, and the morphology of antennae and other appendages. Taxonomic classification within the genus has been subject to revision, and further research may be necessary to fully clarify the relationships between different species.

Ecologically, Disterna beetles play a role in forest ecosystems, both as herbivores and as decomposers. Their wood-boring activity contributes to nutrient cycling within the environment.
